Nowadays, it is possible to integrate an increasing number of functionalities on a single chip thanks to the state of the art technology in Electronic design automation. However, designing highly complex electronic systems quickly and reliably requires dealing with all such functionalities, which can be difficult as it requires a long and challenging design process because low-level details are necessary to obtain a functional implementation. One approach to deal with this complexity is to tackle SoC design from a high-level abstraction standpoint. Then, the numerous functionalities can be described and possibly addressed at a high level, as long as the newly created abstraction gap is taken care of. Time-to-market is of crucial importance when designing a product. A design process done at a high-level of abstraction considerably reduces the time required to obtain the final product. ForSyDe was created to address the problem of moving system design (I.E. System on Chip, Hardware, and Software systems) to a higher level of abstraction and bridge the abstraction gap by transformational design refinement. Currently, ForSyDe is implemented in the functional language Haskell and SystemC. The design flow starts from executable application models with individual design constraints that are a consistent part of ForSyDe ’s goals and this thesis’s primary focus. This thesis project presents the implementation of ForSyDe in the widely used modelling software MATLAB/Simulink. This new implementation allows using the ForSyDe methodology together with the powerful simulation tools offered by Simulink and Matlab. The thesis describes and analyses the different Models of Computation (MoCs) used by ForSyDe. It then presents the ForSyDe methodology and its existing Haskell implementation (on which the Simulink implementation is based). The Simulink simulation engine is introduced to show the differences and similarities with Haskell. The Simulink library developed is based on the ForSyDe-Shallow module (an Embedded Domain-Specific Language part of the Haskell implementation). The limits and opportunities introduced by the Simulink implementation are discussed in this thesis. Like the rest of the documentation, all the existing code is available on the Github repository. The evaluation and comparison of the ForSyDe-Simulink library are also done with a concrete application model that is an Audio Filter subsystem of an audio equalizer system. Simulink is concluded to be more efficient in performance considering the execution time and the memory consumption, but it is not suitable to properly accommodate ForSyDe-Shallow due to a lack of expressiveness.
Tack vare framstegen inom automatisering av design för elektroniska system så är det idag möjligt att integrera mer funktionalitet på ett enstaka chip. Att däremot designa komplexa elektroniska system fort och pålitligt så krävs att alla funktioner hanteras korrekt, vilket kan vara svårt eftersom att det kräver en lång och besvärlig design process eftersom en hel del detaljer krävs för att få en fungerande implementation. Ett sätt att handskas med denna komplexitet är angripa problemet för SoC design genom att använda en hög abstraktionsnivå. Då kan all funktionalitet beskrivas och troligen även adresseras på en hög abstraktionsnivå, så länge man åtgärdar de abstraktions gap som detta orsakar. Tid-till-Marknad är av yttersta vikt då man designar en produkt och en designprocess som utförs på en hög abstraktionsnivå minskar kraftigt tiden till dess att produkten kan framställas. ForSyDe skapades för att adressera problemet med att flytta design av system (t.ex. System on Chip, hårdvara och mjukvarusystem) till en högre abstraktionsnivå och brygga gapet genom att använda transformationer och förfiningar av designen. Just nu så är ForSyDe implementerat i det funktionella språket Haskell och även SyStemC. Designflödet startar med exekverbara modeler av applikationen med individuella design begränsningar som är en del av ForSyDe’s mål och detta examensarbetes primära fokus. Detta examensarbetesprojekt presenterar en implementation av ForSyDe i den välanvända modelleringsmjukvaran MATLAB/Simulnik. Denna nya implementation tillåter användandet av ForSyDe metodologin tillsammans med det kraftfulla simulationsverktyget som tillhandahålls av Simulink och Matlab. Examensarbetet beskriver och analyserar de olika modeller för beräkning (MoCs) som används av ForSyDe. Sedan så presenteras ForSyDe metodologin och dens nuvarande Haskell implementation (som även Simulink implementation baseras på). Simulationsmotorn I Simulink introduceras för att påvisa skillnaderna och likheterna med Haskell. Biblioteket som utvecklats I Simulink baseras på ForSyDe- Shallow modulen (ett inbäddat och domänspecifikt språk som är en del av Haskell implementationen). De begränsningar och möjligheter som introduceras I och med Simulink implementationen diskuteras i detta examensarbete. Likt resten av dokumentationen så finns all kod tillgänglig på Github. En utvärdering och jämförelse av ForSyDe-Simulink biblioteket utförs också med en konkret applikationsmodell som är ett ljudfilter ifrån en ljudutjämnare.

This diploma thesis deals with the implementation of SIL and PIL simulation for the microcontroller Aurix TriCore TC277D performed in the Matlab Simulink. The realization of the simulation represents, among other things, the implementation of the simulated model into the microcontroller, as well as the creation of an interface for the communication of the microcontroller with the Matlab Simulink. The accuracy of SIL and PIL simulations was verified by comparing the simulated waveforms from the simulation in Simulink. The simulated model used a thermal model of a car cabin created in the previous bachelor's thesis of the author of this diploma thesis. The model in TC277D, as well as the configuration for SIL / PIL is created for use with the C programming language. The work also includes instructions according to which the model and configuration can be modified so that the simulations can be performed on any device containing the necessary software. From the comparison of the simulated data is it clear that the created configuration can be used for SIL or PIL simulation.

This thesis studies the techniques of small-signal impedance measurement in three-phase power systems. Stability issue has become critically important since power electronics are highly applied in power distribution and conversion systems. Controlled output systems cause the risk of instability. In order to obtain the impedance model, an impedance extraction in D-Q reference frame algorithm is developed. This paper also applied Interpolated Fast Fourier Transform to increase accuracy of impedance model. Based on the voltage injection, Phase-Locked Loop, Park Transform, D-Q reference frame, and IPFFT. Three-phase system has been realigned on D-Q coordinate and impedance model is extracted in this form. Firstly, impedance extraction algorithm is designed by MATLAB/Simulink, the algorithm includes PLL, D-Q transform, and IPFFT is used to obtain magnitude and phase angle in frequency domain. Impedance matrices in D-Q frame may be solved through the relation between currents and voltages. Impedance model is made through various tests. Secondly, using the algorithm to test RL circuit to verify with real bode plot of the circuit. Then apply the algorithm on sophisticated circuit model. Finally, implement the algorithm on LabView/Multisim for future hardware tests. This paper clearly describes the objective of the research, the research problem and approaches, and experiment setup. This paper presents work conducted at the Smart Grid Power Systems Laboratory at University of South Florida.

Thesis (Masters Degree(Chemical Engineering))--Cape Peninsula University of Technology, 2008
ABSTRACT Carbon-in-pulp (CIP) technology is firmly entrenched in the mining sector due to numerous advances in the last few decades. CIP technology recovers complexed gold in solution from slurry streams by contacting the pulp with carbon and separating the two by screening. The carbon-in-leach (CIL) process, where the pulp contains free cyanide, is closely related to CIP. Both these processes, especially CIL, are complex and are governed by a number of interacting unit processes. The overall process efficiency is dependant on a large number of variables, making the process difficult to optimize. This study uses simple adsorption and leaching rate equations in order to predict dynamic CIL/CIP plant performance under varying operating conditions. This will assist plant metallurgists to achieve optimum efficiency, highlight plant sensitivity to certain variables and will ultimately result in proactive process control. Various assumptions were made in order to keep the modeling considerations as simple and realistic as possible. The process was assumed to have linear kinetic and equilibrium operation. The process was simulated using Simulink in Matlab. Variables are solved on a time step basis by Matlab’s built in optimization algorithms. Simulation results illustrated that the use of simple leaching and adsorption rate expressions are effective for investigating dynamic plant behavior under changing operating conditions.

In dieser Arbeit wurde ein computergestütztes, dynamisches Ein-Spur-Modell eines Pkw mit einem parallelen hybrid-elektrischen Antrieb (P2-Topologie) in Matlab-Simulink entwickelt. Es erlaubt die Skalierung des elektrischen Leistungsanteils und simuliert die Betriebsarten elekt- risches, konventionelles und hybrides Fahren, Bremsenergierückgewinnung und Start-Stopp- Betrieb. Ferner kann durch die Modellierung einer Einscheiben-Trockenkupplung zwischen Verbrennungs- und Elektromotor die Momentenübertragung bei schlupfender Kupplung wäh- rend des Anfahrens oder beim Start des Verbrennungsmotors durch den Elektromotor nach- gebildet werden. Die Fahrzeugsimulation kann in drei verschiedenen Fahrzyklen (NEFZ, WLTP, FTP-75) durchgeführt werden. Als Ausgabegrößen stehen u.a. der Kraftstoffverbrauch, die CO2-Emissionen, die Antriebs- und Rekuperationsarbeit am Verbrennungs- bzw. Elektro- motor und an den Rädern sowie die dafür benötigte bzw. rückgeführte elektrische Energie zur Verfügung. Zusätzlich kann der zeitliche Verlauf zahlreicher relevanter Größen dargestellt wer- den. Die Validierung der Simulation zeigte eine gute Übereinstimmung mit den Daten eines realen Fahrzeuges in Bezug auf Beschleunigungsverhalten, Maximalgeschwindigkeit und Kraftstoffverbrauch
In the frame of this Master Thesis a dynamic single-track-model of a hybrid electric vehicle was developed. The model comprises basic operation modes such as electric, conventional and hybrid driving, recuperation of braking energy and engine start-stop. It allows to scale the split of the propulsion between the combustion and electric engine. A further fundamental com- ponent is the model of a friction disc clutch, enabling the simulation of torque transmission of a slipping clutch during the vehicle start and the upspeeding of the combustion engine through the electric engine. The program offers three driving cycles for simulation (NEDC, WLTC, FTP- 75). Fuel consumption, CO2-emissions, propulsion and recuperation work of the combustion engine, electric engine and the wheels are provided as output variables as well as the required and recuperated electric energy. Furthermore several relevant variables are displayed in their progress over time. The model was validated against real vehicle data showing a good corre- lation regarding acceleration, maximum speed and fuel consumption

Programa computacional em Matlab-Simulink para simular o comportamento do sistema de arrefecimento de veículos comerciais (vans, ônibus e caminhões) equipados com motores diesel. O programa está embasado em uma modelagem matemática que visa caracterizar o funcionamento dos componentes principais do sistema: motor, radiador, termostato, by-pass e bomba d\'água. Tendo como entrada dados característicos do veículo em estudo, o programa computacional fornece a distribuição de temperatura ao longo do tempo para o líquido de arrefecimento - parâmetro preponderante em uma análise do sistema. Os resultados da simulação permitem aos projetistas prever a atuação do sistema de arrefecimento em diversas condições, o que possibilita a realização de um número menor de testes de pista. Os benefícios de um sistema de arrefecimento projetado adequadamente podem ser notados em relação à economia de combustível, ao aumento de desempenho e à redução do desgaste de determinadas peças do motor e da emissão de poluentes.
A software was developed having Matlab-Simulink as basis and it simulates the behavior of the cooling system in commercial vehicles (vans, bus and trucks) equipped with diesel engines. The program is based on mathematical models to describe the main components of the system: engine, radiator, thermostat, by-pass and water pump. Having as input data the features of the vehicle in studied, the software supplies the cooling fluid temperature distribution during certain time - preponderant parameter in the analysis of the system. The results of the simulation allow the designers to foresee the cooling system performance in several conditions, decreasing the number of track tests. The benefits of an adequate designed cooling system project can be noticed considering fuel economy, performance improvement and decrease of wearing of specific parts in the engine as well as pollutant emissions.

The YellowCar at the professorship of computer engineering of TU Chemnitz is a demonstration vehicle. The car is equipped with multiple networked Electronic Control Unit (ECU)s. There are regular software and hardware updates. Before introduction of any new update, it is essential to test the behavior of the car. This can be done through simulation. Since the majority of the ECU in YellowCar are AUTOSAR based, several AUTOSAR simulation tools can be used to do so. However non-AUTOSAR ECU applications can still not be simulated in these tools. Moreover simulating with such tools need the whole application to be implemented and also very expensive. Simulink is one of the most powerful tools for the purpose of Model-in-the-Loop (MIL) testing which is a popular strategy in the embedded world. The scope of this Master thesis is analyzing the YellowCar and its architecture to develop a dynamic Simulink architectural model that can be modified and extended to facilitate future updates. The outcome of this thesis is an implementation of a model for the YellowCar which allows both AUTOSAR and non-AUTOSAR ECUs to be simulated as one system. Also the model supports extension by easy addition of new modules like ECU or sensor through a graphical user interface.

Quantity and intricacy of features implemented in vehicle have expanded rapidly over a past few years. Currently vision of autonomous vehicle is no longer a dream or SF movie, but instead a coming reality. In order to reach the better quality and high safety, advanced verification techniques are required. Simulink Design Verifier is a model checking tool based on formal verification, which can be effectively used to solve problems concerning error detection and testing at earlier stages of project. The transformation of requirements written in traditional form into Simulink Design Verifier objectives can be time consuming as well as requiring knowledge of system model and the verification tools. In order to reduce time consumption and to guide a user through the system model and the verification tool, the semi-automated framework has been developed. An implementation of restricted English grammar patterns into Simulink objects supports description of patterns to engineers and reduces time consumption. The developed framework is flexible and intuitive hence can be a solution for other branches of industry, but further tests and verification would be required. This thesis highlights the whole process of transformation system requirements written in natural language into Simulink Design Verifier objectives. The Fuel Level Display System model currently used by almost all Scania’s vehicles is analysed. Limitations and errors encountered during development process like a flexibility of Simulink Design Verifier to capture requirements and the patterns behaviour or ambiguity of system requirements are analysed and described in this thesis.

Dissertação submetida à Universidade Nova de Lisboa para obtenção do grau de Mestre em Engenharia Electrotécnica e Computadores
O uso de laboratórios remotos no ensino tem vindo a aumentar na última década. Em Portugal, verificou-se um esforço para introduzir laboratórios remotos no ensino básico, secundário e universitário. Hoje em dia são vastas as oportunidades que a Internet oferece no ensino, onde por exemplo são cada vez mais utilizadas técnicas de e-learning que permitem aos alunos uma aprendizagem fora do estabelecimento de ensino. O trabalho de investigação que serviu de base a esta dissertação teve como principal objectivo o desenvolvimento de um sistema de supervisão e controlo de sistemas dinâmicos e a sua aplicação em processos laboratoriais ou industriais. Estes processos apresentam características não lineares e são representativos de sistemas de maior dimensão e complexidade, por exemplo, em processos industriais, sistemas de protecção ambiental ou equipamentos médicos. Esta dissertação oferece uma arquitectura de um laboratório remoto, onde o termo remoto é utilizado com o objectivo de facilitar aos alunos e professores, através da Internet, o acesso a todas as funcionalidades e recursos de um laboratório real. Assim pretende-se eliminar algumas barreiras temporais e geográficas que um laboratório convencional impõe. Para tal foi desenvolvido um simulador em MATLAB/Simulink e em LabVIEW do Benchmark de um sistema de três tanques. Este simulador permitirá o acesso a utilizadores de diversos lugares, que poderão efectuar a prática de um laboratório remotamente e adquirir uma visão completa do mesmo. Neste simulador foram implementados controladores e detectores de oscilação de forma a proporcionar ao utilizador uma série de ferramentas úteis para a realização do trabalho de laboratório.

Le projet de recherche consiste à modéliser et simuler un système multi-domaines complexe sous un unique environnement de travail. Ce système intégrant une partie commande, une partie électrique et une partie mécanique. En effet, la simulation numérique est devenue une tâche incontournable lors de la conception de tout nouveau système et dont l'objectif est la réduction de prototypes et la réduction du temps de la phase de conception. Cet objectif ne peut être complété que par l'utilisation d'outils logiciels adaptés qui sont basés sur la complémentarité entre les différents domaines. C'est pourquoi, ce projet est réalisé sous l'environnement Matlab/Simulink possédant plusieurs modules dédiés aux systèmes mécaniques, électriques et leurs commandes. Afin de se familiariser avec l'environnement Matlab/Simulink, le premier système modélisé est celui de la bobineuse. Ce système que l'on retrouve notamment dans l'industrie papetière consiste à contrôler le couple d'un moteur électrique. Ce dernier entraînant une bobine dont l'inertie et la masse varient à mesure que le papier s'enroule. La seconde étude porte sur le système de transmission d'un véhicule hybride électrique basé sur celui de la Toyota Prius (THS II). Ce système possède en plus de sa source d'énergie primaire provenant du moteur à combustion, une source d'énergie électrique délivrée par une batterie. Le système hybride de la Toyota Prius possède une architecture appelée série/parallèle. Ce système possède un moteur thermique (ou moteur à essence) et deux moteurs électriques. Selon le mode de fonctionnement désiré, le moteur thermique fournit sa puissance mécanique aux roues et/ou entraîne une génératrice permettant d'alimenter le moteur électrique. Ce dernier délivrant alors un couple aux roues. Le moteur électrique pouvant être alimenté par la génératrice et/ou par la batterie. Un système de répartition de la puissance (train planétaire épicycloïdal) permet de diviser la puissance mécanique du moteur thermique entre les roues et la génératrice de façon à utiliser chaque moteur dans sa plage de haut rendement et ainsi augmenter le rendement énergitique du véhicule. Les résultats montrent que les comportements du système mécanique et du système électrique pour chacun des modes de fonctionnement (démarrage, conduite normale, forte accélération, freinage, recharge de la batterie) sont respectés et les caractéristiques dynamiques du véhicule (accélération, vitesse) sont proches de celles rencontrées dans la réalité. Le modèle montre de plus, la complémentarité des outils logiciels de Matlab/Simulink pour simuler des systèmes électromécaniques complexes.

When developing three-phase drives for Electric Vehicles (EVs), it is essential to verify the controller design. This will help in understanding how fast and accurately the torque of the motor can be controlled. In order to do this, it is always better to test the controller using the software version of the motor or vehicle drivetrain than using actual hardware as it could lead to component damage when replicating extreme physical behavior. In this thesis, plant modelling of Permanent Magnet Synchronous Machine (PMSM) and vehicle drivetrain in MATLAB/Simulink for Model Based Design (MBD) is presented. MBD is an effective method for controller design that, if adopted can lead to cost savings of 25%-30% and time savings of 35%-40% (according to a global study by Altran Technologies, the chair of software and systems engineering and the chair of Information Management of the University of Technology in Munich) [1]. The PMSM plant models take effects like magnetic saturation, cross- coupling, spatial harmonics and temperature into account. Two PMSM models in d-q frame based on flux and inductance principles were implemented. Flux, torque maps from Finite Element Analysis (FEA) and apparent inductance from datasheets were used as inputs to the flux- and inductance-based models, respectively. The FEA of PMSM was done using COMSOL Multiphysics. The PMSM model results were compared with corresponding FEA simulated results for verification. A comparison of these PMSM models with conventional low fidelity models has also been done to highlight the impact of inclusion of temperature and spatial harmonics. These motor models can be combined with an inverter plant model and a controller can be developed for the complete model. Low frequency oscillations of drivetrain in EVs lead to vibrations which can cause discomfort and torsional stresses. In order to control these oscillations, an active oscillation damping controller can be implemented. For implementation of this control, a three-mass mechanical plant model of drivetrain with an ABS (Anti-lock Braking System) wheel speed sensor has been developed in this thesis. Analysis of the model transfer function to obtain the pole zero maps was performed. This was used to observe and verify presence of low frequency oscillations in the drivetrain. In order to include the effects of ABS wheel speed sensor and CAN communication, a model was developed for the sensor.
Testning av regulatorernas inställningar med hänsyn till snabbhet och noggrannhet i momentreglering är avgörande i trefasiga drivsystem för elektriska fordon. Oftast är det bättre att simulera i stället för att utföra experimentella tester där komponenter kan skadas på grund av fysisk stress. Detta kallas för Model Based Design (MBD). MBD är an effektiv metod för utformningen av styrningen som kan leda till kostnadsbesparingar på 25%-30% och tidsbesparingar på 35%-40% enligt en studie från Altran Technologies i samarbete med Tekniska universitet i München, TUM. Detta examensarbete behandlar en modell för en synkronmaskin med permanentmagneter (PMSM) samt en modell för drivlinan utvecklad i Matlab/Simulink för MBD. PMSMs modellen inkluderar magnetisk mättnad och tvärkoppling, MMF övervågor och temperatur. Två PMSM modeller har utvecklats. Den första baseras på magnetiskt flöde som erhålls från finita element beräkningar i COMSOL Multiphysics medan den andra bygger på induktanser givna från datablad. En jämförelse av dessa PMSM-modeller med konventionella low fidelity-modeller har också gjorts för att illustrera påverkan temperaturberoende och MMF övervågor. Modellerna kan kombineras med en växelriktarmodell för att utveckla en hel styrenhet. Lågfrekventa oscillationer i drivlinan leder till vibrationer som kan orsaka vridspänningar och försämra komforten i elfordonet. En aktiv dämpningsregulator kan implementeras för att kontrollera spänningarna men en mekanisk drivlinemodell med tre massor och en ABS (anti-lock braking system) hastighetssensor behövs. Den mekaniska modellen har implementerats och analyserats även beaktande en modell för en CAN kommunikationskanal. Oscillationer med låg frekvens kunde observeras i modellen.

Electrical power, although convenient form of energy to distribute and use, cannot easily be stored in large quantities economically. Most electrical power generated by utility plants is consumed simultaneously in real time. However, in some cases, energy storage systems become crucial when power generated from sources does not fulfill peak power load demand in a power system or energy storage systems are needed as backup. Due to these reasons, various technologies such as batteries, ultracapacitors (UC), superconducting magnetic energy storage (SEMS) and flywheels are beneficial options for energy storage systems. Shipboard power systems must use one or more energy storage systems in order to backup the existing power system if locally generated power is unavailable. This will lessen the effect of voltage sags on power quality, and improve system reliability. This report mainly focuses on the design of a Boost DC-DC converter and the integration of that converter with a previously designed battery storage model, as well as the effect of varying loads at the end of the converter.

Radar warning systems are life saving equipment in modern fighter aircraft. It is therefore vital that the system can tell the difference between a threat genuine frequency) and a false signal (spurious frequency).

This thesis presents a model aimed at predicting the frequencies and other parameters in the RF converter of the radar warning system. The components of the RF converter have been studied, measured, and modelled. The modelling tool has been the Simulink toolbox for Matlab.

Extreme accuracy has been sacrificed in order to make the model easy to use for the working engineer. Instead, this model presents a rough estimate of some of the most important properties of the radar warning system with just a few data sheet figures as input.

The simulation results are satisfactory as a whole. Simulink is the limiting factor in the implementation of the model. Significantly improved results can probably be obtained by working in another software environment.

Este trabalho obtém as frequências naturais e seus respectivos modos de vibrar da massa suspensa e não suspensa de um veículo comercial através de um programa computacional desenvolvido em MatLab Simulink. As rodas do veículo são excitadas no modelo teórico com sinais harmônicos de frequência continuamente variável de 0 a 40 Hz e de 0 a 4 Hz, faixas que contém as frequências naturais da massa suspensa e não suspensa. As frequências naturais foram obtidas analisando-se a amplitude máxima das forças normais nos pneus, ângulo de arfagem e rolamento da massa suspensa e outras variáveis (respostas do veículo à excitação imposta na roda dianteira esquerda). A roda esquerda dianteira do veículo foi excitada em laboratório com movimento harmônico aleatório cujo power spectral density mostra uma faixa relativamente plana na faixa de 0 a 22 Hz. As frequências naturais foram obtidas analisando-se o PSD da resposta do veículo medida nos eixos e na massa suspensa. As frequências naturais da massa suspensa e não suspensa obtidas teoricamente foram comparadas com as obtidas no ensaio em laboratório. O conhecimento das frequências naturais da massa suspensa e não suspensa é o primeiro passo para a análise do ride do veículo. Os resultados práticos e teóricos mostraram-se próximos mostrando que o programa computacional desenvolvido em MatLab Simulink é uma opção para o projeto e otimização da suspensão de veículos comerciais.
This study has the natural frequencies and its respective ways of vibration the lifted mass and not lifted of a commercial vehicle through a computerized program developed at MatLab Simulink. The wheels of this vehicle are excited on the theoretic model with harmonic frequency signals continuously variable from 0 to 40 Hz and from 0 to 4 Hz, ranges that have the natural frequencies of the lifted mass and not lifted. These natural frequencies were obtained by analyses of the maximum amplitude of the normal strength on the tires, pitch angle, riding of the lifted mass and variables (reaction of the vehicle to the excitement stressed on the front left wheel). The front left wheel was excited in lab in harmonic random motion of which the power spectral density shows a range reasonable steady at the range of 0 to 22 Hz. The natural frequencies were obtained by the analyses of the PSD the reaction of the vehicle measured on the axels and the lifted mass. The natural frequencies of the lifted and not lifted mass theoretically obtained were compared with the ones obtained at the lab. The data on the natural frequencies of the lifted and not lifted mass is the first step to the analyses of the ride of the vehicle. The practical and theoretical results appear to close showing that the computerized program developed at the MatLab Simulink is an option for the project and suspension upgrades on commercial vehicles.

This thesis describes an improved methodology for embedded software development. MATLAB and Simulink allow engineers to simplify algorithm development and avoid duplication of effort in deploying these algorithms to the end hardware. Special new hardware targeting capabilities of MATLAB and Simulink are described in detail. A motor control system design served to demonstrate the efficacy of this new method. Initial data was collected to help model the motor in Simulink. This allowed for the design of the open and closed loop control systems. The designed system was very effective, with good response and no steady state error. The entire design process and deployment to a digital signal processor took significantly less time and effort than other typical methods. The results of the control system design as well as the details of these development improvements are described.

This master's thesis investigated the possibility to control the clutch torque in order to better traverse a Scania vehicles powertrain backlash. When traversing a backlash the torque difference between the two gears will at the time of contact excite oscillations in the powertrain, and by controlling the torque these oscillations can be minimized. The master's thesis solves this issue in three major steps. First a Simulink model was created to mimic the actual vehicles powertrain as closely as possible. It was created using mostly Simdriveline components and then validated by comparing simulations to measurements from real drives. After that backlash position and backlash size observers were created in order to estimate them. Using the developed Simulink model these observers could then be evaluated, and the backlash position observer proved to be very precise while the backlash size observer was not as precise but still usable. Finally a control strategy was devised, by using the estimates from the developed observers it was supposed to control the clutch torque in a better way than previously done. The controller was a switching controller that simply used the full engine torque while the backlash was in contact, and a P controller to control the clutch torque while performing a backlash traverse. The controller proved to perform well and was robust to errors in the backlash size. Future work to be done could be to develop a shaft torque observer for use in the already developed observers.

With upcoming stricter emission legislations and increasing fuel prices reducing fuel consumption, i.e. CO2 emissions, are one of the driving forces behind development in the automobile industry. One solution to reduce fuel consumption is hybridization, giving the vehicle overall higher engine efficiency. In this thesis it has been investigated if it is possible to reduce fuel consumption via hybridization with maintained performance for different hybrid topologies and degree of hybridization. This is investigated by developing models in Matlab/Simulink which are used in the AVL rapid prototyping’s plant model. Results from the simulations shows that there are vehicle layouts that would comply with set demands (fuel consumption and performance) both when using parallel and series topology. The conclusion is that the fuel consumption reductions are large enough to make it interesting with hybridization, however further investigation is needed to determine if the increased costs would make hybridization beneficial.
Stigande bränslepriser och framtida lagkrav har gjort att minskad bränsleförbrukning (CO2-utsläpp) är en av de drivande krafterna i utvecklingen hos dagens bilindustri. Ett sätt att lösa detta är med hjälp av hybridisering, som låter förbränningsmotorn arbeta på bättre effektivitetspunkter. I det här projektet har det undersökts om det är möjligt att reducera bränsleförbrukningen och samtidigt bibehålla fordonets prestanda med hjälp av olika hybridiseringsstrategier och -grader. Undersökningen har utförts genom att modeller har tagits fram i Matlab/simulink och sedan använts med simuleringsverktyget i AVLs rapid prototyping styrsystem. Resultaten från dessa simuleringar visar på att det finns fordon med komponentkombinationer som uppfyller kraven på lägre bränsle förbrukning och prestanda för både parallell- och seriehybrider. Slutsatsen är att bränslebesparingarna är tillräckligt stora för att göra hybridisering intressant, dock behövs vidare undersökningar om huruvida det är ekonomiskt hållbart med hybridisering.

The use of renewable energy sources is increasing and will play an important role in the future power systems. The unpredictable and fluctuating nature of solar power leads to a need for energy storage as the prevalence increases.A five parameter model of PV modules has been implemented in Simulink/Matlab. The parameters of the model are determined by an approximation method using data sheet values. Inputs to the model include light intensity and ambient temperature. The outputs are any measurements of interests as well as power, cell temperature and voltage. Effects of varying the model parameters are demonstrated. A maximum power point tracking algorithm is used to keep the voltage at the maximum power point at all times.A battery model based on discharge curve fitting is implemented. The model is based on a fundamental battery cell which can be modified to construct many different module configurations. Power smoothing algorithms which average the input over a set time, are used to provide a power reference to the battery system.The PV model power output is compared to in-situ measurements by giving the model inputs of measured irradiance profile and ambient temperature. Measurements of two different days, one with little variation in irradiance and one with a lot of variation, are used to shed light on different effects. The difference between the output of the simulation and the measured values is very small, in the range of a few percent, especially when there is little variation in irradiance. Large peaks in difference are probably caused by the maximum power point tracking not being able to follow rapidly changing conditions.The approximation used in the modelling of cell temperature deviates significantly from the measured cell temperature. This is confirmed as one of the largest causes of deviance by running simulations with actual measured cell temperature.Power smoothing efficiency is demonstrated with different battery module sizes. Changing the power smoothing algorithm parameters to suit the battery capacity is shown to be effective in providing as good smoothing as possible within battery constraints.

As distributed generations and renewable energy are becoming the fastest growing segment of the energy industry, the technical issues and environmental impacts have to be studied and understood. The large number of small-scale Microgrid components with their own characteristics is a big challenge for Microgrid modeling, simulation, planning and operation.

The major goal of this thesis is to build a library of various Microgrid components. First of all, the thesis is going to present a detailed description of Microgrid models with moderate complexity. Next, it will present the modeling of loads, utility grid and transmission lines. Then, the paper will discuss the distributed generation models that have been developed in Matlab/Simulink including Diesel Engine, Fuel Cell, Micro Gas Turbine, Wind Turbine, Photovoltaic Cell, along with the detailed modeling of short-term storage (Battery, Pumped Hydro Storage, Flywheel, and Supercapacitor). In addition to steady-state study, the thesis will also discuss the hybrid sample systems that are built to investigate their transient responses.

To enhance the simulation performance, some improvements on modeling and simulation will be introduced as well. To accommodate the high demand of renewable energy and the environment policy, the planning and operation the of Micro-source generators has been studied using HOMER. Simulation results show a case study of an optimal microgrid configuration on Ontario area in Canada. Sensitivity variables are specified to examine the effect of uncertainties, especially in a long-term planning. Also, demand side management plays an important role in the operation of Microgrid. Based on raw data, case studies are carried out to investigate and validate the demand response methods. Finally, the philosophy for Microgrid protection, especially Time-delay overcurrent protection, will be briefly introduced in both gird-connected and islanding modes.

Foi desenvolvido um conversor, de nome Matlaber, que recebe código CLP em linguagem IL e o converte automaticamente para um ficheiro ".m", compatível com o ambiente Matlab/Simulink. Este ficheiro será uma função Matlab que simula um CLP correndo um programa equivalente ao original, para uso no ambiente Simulink. O trabalho desenvolvido inclui também um tradutor de códigos CLP proprietários, de nome UnifIL, que normaliza o código CLP proprietário em código IL. Com estes dois elementos, torna-se possível emular o funcionamento de programas de controlo de CLP proprietários, em ambiente Matlab/Simulink. A tradução do código proprietário é feita com recurso a dicionários de regras e tradução próprios, sendo portanto expansível a várias linguagens de CLP de baixo nível, desde que um dicionário adequado seja criado. Para a prova de conceito foram criados 2 dicionários para linguagens proprietárias: Siemens Step 7 (STL série 200) e Mitsubishi Q Series (List Mode).

The Cal Poly Sustainable Power for Electrical Resources (SuPER) project is a solar power DC distribution system designed to autonomously manage and supply the energy needs of a single family off-the-grid home. The following thesis describes the improvement and re-design of a MATLAB Simulink model for the Cal Poly SuPER system. This model includes a photovoltaic (PV) array, a lead-acid gel battery with temperature effects, a wind turbine model, a re-designed DC-DC converter, a DC microgrid, and multiple loads. This thesis will also include several control algorithms such as a temperature controlled thermoelectric (T.E.) cooler, intelligent load switching, and an intelligent power source selector. Furthermore, a seven day simulation and evaluation of the results are presented. This simulation is an important tool for further system development, re-design, and long term system performance prediction.

Det här rapporten är en del av mitt examensarbete för högskoleingenjörsexamen i elektroteknik vid Växjö Universitet, MSI. Arbetet är en del av ett större projekt kallat Kranstyrningsprojektet som bedrivs av Växjö Universitet, Rottne Industri med flera, vars syfte är att underlätta för förare att kontrollera den kran som finns på Rottnes skotare. För projektet har det använts en laborationskran och nu har önskemålet varit att det till kranen ska installeras ett nytt styrsystem från dSPACE. Dessutom vill man att nya givare ska sättas på kranen och kopplas till dSPACE. Man vill även ha en manual för att nya studenter ska kunna använda systemet. Det nya dSPACE-systemet består av en datorlåda med processor- och I/O-kort. Man kommunicerar med dSPACE från en PC. Arbetet med installationen har stött på flera problem och arbetet har dragit ut på tiden. När systemet till slut gick att använda utfördes ett par tester och sen implementerades det på kranen. Arbete med att ta fram underlag för installation av accelerometrar på kranen pågick samtidigt och en jämförelse mellan olika alternativ gjordes. Arbetet resulterade i att laborationskranen nu går att styra med det nyinköpta systemet från dSPACE och en manual skapades för att underlätta användandet av systemet.

This document is a part of my bachelor degree thesis in electronic engineering was done at Växjö University, MSI. This work is a part of a bigger project called Crane Tip Control which is pursued by Växjö University, Rottne Industri and others, whose purpose is to facilitate for drivers to control the crane used on forwarders from Rottne. For this project, a laboratory crane has been used and they requested that a new control system from dSPACE was installed to the crane. Also they want new sensors to be placed on the crane and connected to dSPACE. A manual should also be created for new students who want to use the system. The new dSPACE-system consists of a computer box with processor- and I/O-boards. Communication with dSPACE is done via a PC. The work with the installation has encountered many problems and the work has been overrun. When the system finally was working, some tests were performed and then the system was installed at the crane. A task to assemble data for installation of accelerometers, was done during the same time and a comparison between different alternatives was made. The work resulted in the laboratory crane is now able to be controled by the new dSPACE-system and a manual was created to facilitate the usage of the system.

The forwarder acts as an important role in mechanized Cut-to-Length timber harvesting system. But the majority of forwarder products on the market are not suspended or simply suspended by bogies which limit the riding quality of forwarder and result in soil damage due to large tireground interaction force. The Forestry Research Institute of Sweden is developing an active controlled pendulum arm suspension system actuated by hydraulic cylinders on the forwarder prototype named XT28. The aim of this active suspension system is to compensate the inherent shortcomings of the current suspension solutions. The thesis project focuses on implementing a heterogeneous simulation methodology which integrates the Multi-Body System model of XT28 built in MSC ADAMS/View with active suspension control model developed in MATLAB/Simulink. Thus, the co-simulation process is visualized in ADAMS/View. The results show that the active controlled pendulum arm suspension could improve the riding quality in a large extend and reduce the force between tire and ground at the same time. The cosimulation between ADAMS and Simulink is proved as a feasible and efficient approach to study the active control system for pendulum arm suspension on XT28 forwarder.
Skotaren har tillsammans med skördaren en central roll i den fullt mekaniserade kortvirkesmetoden för skogsavverkning. Majoriteten av dagens skotare på marknaden har sex eller åtta hjul, som är monterade parvis på boggilådor. Det innebär att de saknar chassidämpning, vilket begränsar operatörens komfort och orsakar även stora markskador på mjuk mark. Skogforsk koordinerar realiseringen av en fullskaleprototyp, som går under arbetsnamnet XT28, med sex hjul monterade på varsin pendelarm. Pendelarmarna har varsin hydraulcylinder som möjliggör aktiv helmaskinsdämpning. Detta examensarbete är inriktat på att skapa, demonstrera och verifiera en heterogen simuleringsmetodik, som integrerar och möjliggör samsimulering av en dynamisk mekanikmodell utvecklad i MSC Adams/View med en reglermodell för aktiv styrning av pendelarmarna. Reglermodellen har utvecklats i MATLAB / Simulink. Simuleringsresultaten, som visualiseras i Adams-miljön, visar att den aktiva pendelarmregleringen skulle kunna förbättra åkkomforten signifikant, och också kraftigt markkontaktkrafterna. Det visas att samsimulering mellan ADAMS och Simulink är en effektiv metod för att verifiera prestandan hos aktiva reglersystem för pendelarmsfjädring på prototypskotaren XT28.

Este trabalho propõe a arquitetura para uma Plataforma de Testes de sistemas de piloto automático voltada para ambiente de simulação. Trata-se de uma ferramenta com propósitos educacionais e de pesquisa onde variadas configurações destes sistemas podem ser facilmente implementadas aumentando a flexibilidade dos testes executados e acelerando seu desenvolvimento. Por se tratar de ambiente de simulação, apresenta vantagens como a facilidade de operação e a obtenção de resultados em bancada imediatamente após o projeto do sistema, o que antecipa a detecção de problemas que poderiam ser encontrados somente após sua implementação. Estas características apresentam-se ideais para suportar o processo de desenvolvimento de sistemas de piloto automático para VANTs (Veículos Aéreos Não Tripulados) considerando a necessidade de testes intensivos antes de embarcar estes sistemas. Nesta Plataforma de Testes é utilizado o Matlab/Simulink contendo o modelo do sistema de controle de piloto automático a ser testado, o simulador de vôo X-Plane contendo o modelo da aeronave a ser controlada, um microcontrolador para controle das superfícies de comando de vôo de um aeromodelo e servos eletromecânicos para acionamento destas superfícies. Estes recursos são interligados através de barramentos de dados para troca de informações. Após uma exposição dos conceitos do movimento de uma aeronave rígida e suas equações, a Plataforma de Testes proposta é descrita em detalhes, pois este é o assunto principal do presente trabalho. Para demonstração da validade do projeto, comparam-se os resultados da simulação executada no Matlab/Simulink de um controlador de piloto automático previamente projetado com aqueles obtidos pela integração do mesmo controlador na Plataforma de Testes.
