Повний текст джерелаThe engine torque is an important control signal. This signal is disturbed by the devices mounted on the belt. To better be able to estimate the torque signal, this work aims to model the auxiliary devices'influence on the crankshaft torque. Physical models have been developed for the air conditioning compressor, the alternator and the power steering pump. If these models are to be used in control unit function development and testing, they have to be fast enough to run on a hardware-in-the-loop simulator in real time. The models have been simplified to meet these demands.
The compressor model has a good physical basis, but the validity of the control mechanism is uncertain. The alternator model has been tested against a real electronic control unit in a hardware-in-the-loop simulator, and tests show good results. Validation against measurements is however necessary to confirm the results. The power steering pump model also has a good physical basis, but it is argued that a simple model relating the macro input-output power could be more valuable for control unit function development.

According to the International Energy Agency (IEA), electric power usage is increasing across all sectors, and particularly in the transportation sector [1]. This increase is apparent in one's daily life through the increase of electric vehicles on the road. Power electronics convert electricity in one form to electricity in another form. This conversion of power is playing an increasingly important role in society because examples of this conversion include converting the dc voltage of a battery to ac voltage in an electric car or the conversion of the ac power grid to dc to power a laptop. Additionally, even within an electric car, power converters transform the battery's electric power from a higher dc voltage into lower voltage dc power to supply the entertainment system and into ac power to drive the car's motor. The electrification of the transportation sector is leading to an increase in the amount of electric energy that is being consumed and processed through power electronics. As was illustrated in the previous examples of electric cars, the application of power electronics is very wide and thus requires different testbenches for the many different applications. While some industries are used to power electronics and testing converters, transportation electrification is increasing the number of companies and industries that are using power electronics and electric machines. As industry is shifting towards these new technologies, it is a prime opportunity to change the way that high power testing is done for electric machines and power converters. Traditional testing methods are potentially dangerous and lack the flexibility that is required to test a wide variety of machines and drives. Power hardware-in-the-loop (PHIL) testing presents a safe and adaptable solution to high power testing of electric machines. Traditionally, electric machines were primarily used in heavy industry such as milling, processing, and pumping applications. These applications, and other applications such as an electric motor in a car or plane are called motor drive systems. Regardless of the particular application of the motor drive system, there are generally three parts: a dc source, an inverter, and the electric machine. In most applications, other than cars which have a dc battery, the dc source is a power electronic converter called a rectifier which converts ac electricity from the grid to dc for the motor drive. Next, the motor drive converts the dc electricity from the first stage to a controlled ac output to drive the electric machine. Finally, the electric machine itself is the final piece of the electrical system and converts the electrical energy to mechanical energy which can drive a fan, belt, or axle. The fact that this motor drive system can be generalized and applied to a wide range of applications makes its study particularly interesting. PHIL simplifies testing of these motor drive systems by allowing the inverter to connect directly to a machine emulator which is able to replicate a variety of loads. Furthermore, this work demonstrates the capability of PHIL to emulate both the induction machine load as well as the dc source by considering several rectifier topologies without any significant adjustments from the machine emulation platform. This thesis demonstrates the capabilities of the EGSTON Power Electronics GmbH COMPISO System Unit to emulate motor drive systems to allow for safer, more flexible motor drive system testing. The main goal of this thesis is to demonstrate an accurate PHIL emulation of a induction machine and to provide validation of the emulation results through comparison with an induction machine.

Повний текст джерелаAutomotive PEM Fuel Cell systems rely upon a set of auxiliary systems for proper operation, such as humidifier, air-feed compressor, power converter etc. The internal physical states of the latter are often unmeasurable, yet required for their precise control. Observers provide a means of obtaining the unmeasured states of these auxiliary systems for feedback control, optimal energy consumption and Fault Diagnosis and Isolation (FDI). This thesis is based on higher order sliding mode observer design studies for two major PEMFC auxiliary systems found in modern automobiles, the air-feed system and the power electronics system.The first part is focused on robust observation and FDI of the PEMFC air-feed systems. Sliding mode observer design and their applications to FDI have been studied in detail for this purpose and the key observation problems in this system have been identified. Based on this study, two solutions are proposed, a sliding mode algebraic observer for oxygen and nitrogen partial pressures and a novel robust adaptive-gain Second Order Sliding Mode (SOSM) observer based FDI for simultaneous state observation, parameter identification, health monitoring and fault reconstruction of the PEMFC air-feed system. The performance of the proposed observers has been validated on an instrumented Hardware-In-Loop (HIL) test bench.The observation and output feedback control problems of different power electronic converters, commonly found in fuel cell vehicles, are addressed in the next part. Robust output feedback SOSM control for three phase AC/DC converters have been presented. A robust SOSM observer for multi-cell converters has also been designed. The performance of all these designs has been demonstrated through a multi-rate simulation approach. The results highlight the robustness of the observers and controllers against parametric uncertainty, measurement noise and external disturbance

Повний текст джерелаThe electrical power generation in remote maritime areas must face many technical-economicconstraints related to the load satisfaction and the expensivefuel import for fossil based sources. Thanks to the recent development of marine renewable energies, new perspectives appearfor the electrical power supply of maritime remote areas, so asto decarbonize the electrical power generation. In this thesis, it is proposed to study the sizing and the energy management of anislanded microgrid madeof solar photovoltaic panels, wind turbines, tidal turbines, wave energy converters and batteries. A preliminary analysis of the harnessed resources allows some complementarities and non-complementaritiesto be highlighted. In order to reduce the unmet load demand and the cost of energy, a combined sizing and energy management optimization isproposed. Several demand-side management strategies are hierarchically applied on several loads, in order to avoid the occurrence of critical situations. The obtained results show that demand-side management allows the cost of energy to be reduced by decreasingthe amount of required storage. Also, thediversification of the sources brings many benefits. Finally, the ability of the developed algorithms tocorrectly manage the micro-grid in real time is validated on an experimental test bench

Повний текст джерелаA Fuel cell (FC) hybrid power system is a promising solution to deal with the atmospheric pollution and fossil fuels shortage problems. This thesis focuses on the controller design for FC hybrid power systems, towards two applications: the hybrid electrical vehicle and the microgrid-powered datacenter.Firstly, this thesis proposes an advanced passivity-based control for a FC/super-capacitors (SCs) hybrid system. In order to solve the converters coordination problem, a controller designed using the design method Interconnection and Damping Assignment - Passivity-Based Control (IDA-PBC) is applied, which considers the state-of-charge of the SCs as well as voltage and current limitations. The proposed controller is validated on a Power Hardware-in-the-loop (PHIL) platform. Then an Extended Kalman Filter (EKF) is applied to forecast the State-of-Health (SoH) of the fuel cell and is combined with the proposed controller. Finally, a Hardware-in-the-loop (HIL) platform based on an INTEL/ALTERA FPGA is designed in order to validate the real-time operation of the algorithms for a specific case study with a commercial vehicle.For microgrid applications, a passivity-based controller for a hybrid power supply system for a green datacenter is proposed, including photovoltaic panels, a fuel cell, SCs and an electrolyzer. The feasibility of this non-linear controller is proven by the simulation results and experimental validation on a PHIL test bench. This work is integrated into the ANR DATAZERO project.The main novelty of the proposed controller is that it integrates some component constraints directly into the controller equations, while the locally asymptotic stability of the whole closed-loop system is preserved

Esta dissertação apresenta um estudo de um conversor emulador de rede (CER) que faz parte de uma estrutura Power-Hardware-in-the-Loop (PHIL). O PHIL será futuramente utilizado para verificar os impactos causados pela integração de sistemas de geração fotovoltaico (PV) à rede elétrica, assim como a operação do sistema PV frente a distúrbios na rede. O CER, composto por um conversor fonte de tensão (VSC) de dois níveis e filtro de saída LC, é responsável por alimentar cargas isoladas emulando uma rede elétrica. A modelagem do conversor emulador de rede é feita no sistema de coordenadas estacionário (αβ0), fornecendo um sistema de equações diferenciais usado para descrever o comportamento dinâmico do sistema. O conversor é controlado no modo de tensão, através da estratégia de modulação vetorial. Duas malhas de controle em cascata são projetadas. A malha interna utiliza compensadores em avanço digitais para amortecer a ressonância do filtro LC sem a necessidade de uma realimentação interna de corrente. Já a externa utiliza controladores ressonantes digitais modificados para rejeitar distúrbios harmônicos e garantir a qualidade da forma de onda da tensão no ponto de acoplamento comum. Os controladores ressonantes são conectados em série e o projeto é baseado no amortecimento dos zeros. Resultados experimentais, obtidos com o protótipo de laboratório, cujos controladores foram implementados em um processador digital de sinais TMS320F28335 da Texas Instruments, são usados para validar as estratégias de controle propostas.
This dissertation presents a study on a grid-former converter (GFC) which is a part of a Power-Hardware-in-the-Loop (PHIL) structure. The PHIL will be used to verify the impacts caused by the integration of photovoltaic (PV) generation systems into grid, as well as to study the PV operation under grid disturbances. The GFC, composed by a two-level voltage source converter with a LC output filter, is responsible to feed isolated loads emulating an electrical grid. The modeling of the grid-former converter is done in the stationary frame (αβ0), providing a set of differential equations that describes the dynamical behavior of the system. The converter is controlled in voltage mode by means of the space vector modulation (SVM) strategy. Two control loops are designed to control the static converter. At the inner loop a novel discrete-time active damping technique is proposed in order to damp the filter resonance without the need of current feedback. The method is based on an inner feedback loop with digital lead compensator on the feedback path while the external loop uses a discretetime integrator and a modified digital resonant controller to guarantee a decreasing frequency response and ensure the quality of the voltage waveform at the point of common coupling, respectively. The resonant controllers are connected in series and the design is based on its zeros damping. Experimental results obtained with the prototype, which controllers were implemented in a Texas Instruments TMS320F28335 are used to validate the proposed control strategies.

Повний текст джерелаWith the development of fuel cell (FC) and water electrolysis technologies, electrolytic hydrogen is becoming a pillar of the energy transition, a substitute for fossil resources and a tool for integrating intermittent renewable energy sources (RES). On the scale of isolated or islandable microgrids, this transition is based on the development of hybrid systems, coupling photovoltaic (PV) panels and electrolyzers for hydrogen production, storage systems - hydrogen (H2) tanks and batteries (Bat) - and FC for electricity production. This study presents control strategies for a PV-H2-Bat-FC system to optimize intermittent PV energy management while respecting the operating conditions of electrolyzers and FC. First, a MPPT (Maximum Power Point Tracking) control system is developed to ensure the operation of PV at maximum power, and a control strategy based on Model Predictive Control is implemented to define a current reference for the FC, the electrolyzer and the batteries. Secondly, IP controllers are used to regulate these currents. Thirdly, an optimization problem makes it possible to define a commitment plan to use the FC and the electrolyser taking into account energy supply, demand and stocks

Повний текст джерелаThe control of Electric Power Assisted Steering (EPAS) system is a challengingproblem due to the multiple objectives and the need of several pieces of information to implement the control. The control objectives are to generate assist torque with fast responses to driver’s torque commands, insure system stability, attenuate vibrations, transmit the road information to the driver, and improve the steering wheel returnability and free control performance. The control must also be robust against modeling errors and parameter uncertainties. In addition, several pieces of information are required to implement the control, such as steering wheel angle, motor velocity, driver torque and road reaction torque

Повний текст джерелаIndustrial controllers are always subjected to parameters change, modifications and permanent improvements. They have to follow off-the-shelf technologies as well as hardware than software (libraries, operating system, control regulations ...). Apart from these primary necessities, additional aspects concerning the system operation that includes sequential, protections, human machine interface and system stability have to be implemented and interfaced correctly. In addition, these functions should be generically structured to be used in common for wide range of applications. All modifications (hardware or software) even slight ones are risky. In the absence of a prior validation system, these modifications are potentially a source of system instability or damage. On-site debugging and modification are not only extremely expensive but can be highly risky, cumulate expenditure and reduce productivity. This concerns all major industrial applications, Oil & Gas installations and Marine applications. Working conditions are difficult and the amount of tests that can be done is strictly limited to the mandatory ones. This thesis proposes two levels of industrial controller validation which can be done in experimental test platform : an algorithm validation level called Software In the Loop (SIL) treated in the second chapter ; a physical hardware validation called Hardware In the Loop (HIL) treated in the third chapter. The SIL validates only the control algorithm, the control law and the computed references without taking into account neither the actual physical commands nor the physical input feedbacks managed by the Input/Output boards. SIL validation of the system where industrial asynchronous motor is fed and regulated by a three level Variable Speed Drive with a three level voltage source converter is treated in the second chapter with a particular modeling approach adapted to such validation. The last chapter presents the HIL validation with various hardware implementations (Field Programmable Gate Array (FPGA), processors). Such validation checks both the control algorithm and the actual physical Input/Output signals generated by the dedicated boards. Each time, the modeling approach is chosen according to the hardware implementation. Currently this work has contributed to the system validation used by General Electric - Power Conversion © (GE-PC) as part of their validation phase that is mandatory for Oil & Gas projects and Marine applications

Повний текст джерелаAdvanced computer simulations will play a more and more important role in future aircraft development and aeronautic research. Hardware-in-the-loop simulations enable examination of single components without the need of a full-scale model of the system. This project investigates the possibility of conducting hardware-in-the-loop simulations using a hydraulic test rig utilizing modern computer equipment. Controllers and models have been built in Simulink and Hopsan. Most hydraulic and mechanical components used in Hopsan have also been translated from Fortran to C and compiled into shared libraries (.dll). This provides an easy way of importing Hopsan models in LabVIEW, which is used to control the test rig. The results have been compared between Hopsan and LabVIEW, and no major differences in the results could be found. Importing Hopsan components to LabVIEW can potentially enable powerful features not available in Hopsan, such as hardware-in-the-loop simulations, multi-core processing and advanced plotting tools. It does however require fast computer systems to achieve real-time speed. The results of this project can provide interesting starting points in the development of the next generation of Hopsan.

Повний текст джерелаENGLISH ABSTRACT: A multiprocessor hardware-in-the-Ioop operating system was developed for the Integrated Test System (ITS) and is aimed at implementing the ITS as a space emulation vehicle. The thesis contains a study of satellite orbits, Kepler elements, geomagnetic fields and communication protocol between the processors. The system structure consists of an orbit generator, a core-operating system and is presented with a study of the satellite sensors. In implementing the orbit propagator, there was a need to pay special attention to the Halving algorithm, the Newton Raphson method and the True Solution. These algorithms were used to calculate the true anomaly angle as a function of eccentric anomaly. The communications protocol was tested and all the errors, with their solutions, have been discussed. A concept of a geomagnetic field emulator has also been included in the hardware-in-theloop operating system. The evaluation of those aspects of the system and the conclusion are presented together with recommendations.

Повний текст джерелаDenna rapport är resultatet av ett examensarbete utfört på Elekta AB under hösten 2013 och våren 2014. Elekta är ett medicintekniskt företag vars huvudprodukt på Stockholmskontoret är en gammakniv som används inom radiokirurgi. Gammakniven innehåller ett kluster av ett dussin motorservon styrda över en CAN-buss. Dessa används för att justera patienten och de radioaktiva källorna. För tillfället använder företaget en egenutvecklad ”Hardware-in-the-Loop” simulator, körandes på en PC med LabVIEW, för att utföra integrationstester av gammaknivens styrsystem. Simulatorn har uppvisat tecken prestandaproblem och att simuleringarna inte sker i realtid. Elekta misstänker att detta beror på det stora antalet meddelanden som måste hanteras över CAN, seriella och andra anslutningar. Företaget är motvilligt att investera i dyra färdiga system och vill undersöka möjligheten att lösa dessa problem genom att implementera den nuvarande simulatorn på ett billigt inbyggt system.Projektets fokus har legat på att undersöka om det är möjligt att ersätta den nuvarande HIL simulatorn med ett billigare inbyggt system. Detta gjordes genom att bygga en ”proof-of-concept” prototyp för att demonstrera att detta är möjligt.Relaterat till detta problemområde genomfördes en fallstudie på Elekta om hur företaget arbetar med validering, verifiering och testning. Syftet med studien var att undersöka om det finns några förändringar som företaget kan göra för att förbättra denna process. Detta gjordes genom att utföra en litteraturstudie och genomföra intervjuer med utvecklare och testare på företaget.Ett återskapande av den nuvarande HIL simulatorns huvudfunktionalitet implementerades på en STM32F103 mikrokontroller from STMicroelectronics som använder en ARM Cortex M3 processor med ARM7 arkitektur. Mikrokontrollern kunde framgångsrikt samverka med styrsystemet och simulera klustret av motorservorna och deras mekaniska system med tillräcklig realtidsprestanda.De dragna slutsatserna är att det är möjligt för Elekta att implementera funktionaliteten av deras nuvarande HIL simulator på en Cortex M3 mikrokontroller. Företaget behöver dock undersöka om en flytt av den nuvarande simulatorn kommer att göra ytterligare utveckling och användande av systemet mera komplicerat och kostsamt.

Повний текст джерелаI produktionsbranscher finns det en ständig efterfrågan på kortare tid till marknad och lägre utvecklingskostnader. Modeller och simuleringar har visat sig vara ett sätt att minska utvecklingstiden och öka produktkvalitén. En anledning till detta är att dessa metoder tillåter utveckling och testning av styrsystem innan de faktiska fysiska prototyperna är tillgängliga.Syftet med detta examensarbete är att genomföra en realtids simulering av lödpastaskrivaren MY500 som tillverkas av Micronic Mydata AB. MY500 har hög krav på noggrannhet och hastighet, vilket resulterar i en kort samplingstid som i sin tur sätter hårda restriktioner på modellens beräkningstid. Simuleringen genomförs på en dSPACE MicroAutoBox tillsammans med simuleringsverktyg i MATLAB. närmare bestämt Simulink och SimMechanics. Simulatorn kommunicerar med styrsystemet via SPI och implementerar en befintlig SimMechanics modell och en nyutvecklad Simulink modell. Simulink modellen, som utvecklats i detta examensarbete, visade sig vara en tillräckligt realistisk förenkling av SimMechanics modellen. Vidare visar resultaten att SimMechanicsmodellen inte kan köras på den valda hårdvaran p.g.a. dess komplexitet. Studien visar också att, när den interna klockan används, även med det kortaste tidssteget som hårdvaran klarar av, kommer inte HIL simuleringen att vara stabil. Slutligen, SPI-kommunikationen som testas introducerade fördröjningar i MY500 reglerloopen, vilket ledde till att systemet enbart kunde beräkna en axel. Slutsatsen som dras är att även om den nuvarande tillämpningen har nackdelar, finns det ändå skäl för att fortsätta arbetet och att göra en bra simulator. De två mest relevanta utvecklingar är: för det första, implementeringen av en extern interrupt borde tillåta ett större tidssteg och även eliminera jitter i modellens output. Sedan, med att flytta SPIkommunikationskoden ur reglerloopen och istället implementera den direkt på en FPGA borde beräkningsfördröjningar, komna från SPI, minimeras och därmed kontroll av mer än en axel möjliggörs.

Повний текст джерелаRF Communication (COMMS) systems where receivers and transmitters are in motion must be proven rigorously over an array of natural RF link perturbations such as Carrier Doppler shift, Signal Doppler shift, delay, path loss and noise. These perturbations play significant roles in COMMS systems involving satellites, aircraft, UAVs, missiles, targets and ground stations. In these applications, COMMS system devices must also be tested against increasingly sophisticated intentional and unintentional interference, which must result in negligible impact on quality of service. Field testing and use of traditional test and measurement equipment will need to be substantially augmented with physics-compliant channel emulation equipment that broadens the scope, depth and coverage of such tests, while decreasing R&D and test costs and driving in quality. This paper describes dynamic link emulation driven by advanced antenna and motion modeling, detailed propagation models and link budget methods for realistic, nominal and worst-case hardware-in-the-loop test and verification.

Повний текст джерелаFör att förbättra elnätets transientstabilitet och dämpning kan kompletterandestyrenheter användas på inbäddade högspänningslikströmslänkar (HVDC). Arbetetsom presenteras i denna rapport syftade till att validera Dynamic Virtual Admittance(DVA) reglering, utvecklat i SuperGrid Institute, i simuleringar med mjukochhårdvara-i-loop (SIL & HIL).DVA studerades först analytiskt och implementerades i en offlinesimulering, påett grundläggande provsystem. Ett testsystem i två områden modellerades sedansom bas för validering av regleringens stabilisering. Felet som användes för attprova styrenhetens effektivitet var en trefas kortslutning på en av de växelströmsledningarsom förbinder de två områdena. DVAC validerades på provsystemet,först av SIL och sedan av HIL realtidssimulering. För att omvandla simuleringen tillen HIL-simulering implementerades DVAC i kod C i en Raspberry Pi-dator, och IEC61850-kommunikationsprotokollet studerades i detalj för att konfigureras för HILsimuleringensuppsättning.SIL och HIL simulering av DVAC validerades för en trefasig kortslutning ochbekräftade att regleringen kunde dämpa ut effektoscillationerna inom 5 sekunder,dubbelt så snabbt jämfört med om ingen reglering var implementerad.

Повний текст джерелаUm ambiente simulado é a via mais rápida, e de menores custos, para avaliar o desempenho de diferentes estratégias para controlo de sistemas hidráulicos. Neste campo emerge uma nova técnica, denominada simulação com hardware-in-the-loop (HILS), para teste de controladores reais em ambientes virtuais simulados em tempo real. A presente dissertação propõe uma metodologia para a organização de bibliotecas de modelos, um conjunto de modelos híbridos semi-empíricos para componentes de sistemas hidráulicos e uma plataforma para a realização de experiências de simulação com hardware-in-the-loop. A metodologia proposta baseia-se na associação de uma nova linguagem de modelação orientada por objectos, chamada Modelica, para a descrição da estrutura dos modelos, com o formalismo gráfico dos Statecharts para a descrição do seu comportamento híbrido. Tendo em vista a concretização da metodologia, foi desenvolvida uma biblioteca de modelos para a implementação do formalismo dos Statecharts em Modelica. Entre os modelos para componentes hidráulicos propostos está um conjunto de modelos semi-empíricos para a modelação de válvulas proporcionais de elevado desempenho. Os modelos desenvolvidos usam dados do fabricante ou dados experimentais para ajuste dos parâmetros, de forma a reproduzir as características estáticas (ganho de pressão, caudal de fugas e ganho de caudal) e dinâmicas (resposta em frequência) da válvula. Foi construída uma plataforma para teste do desempenho dos modelos híbridos desenvolvidos em simulações com hardware-in-the-loop. A plataforma é composta por um manipulador com actuação hidráulica equipado com um conjunto de transdutores, por hardware de tempo real e por um conjunto de ferramentas de software para aquisição de dados e controlo. De um conjunto de experiências HILS, realizadas com diferentes núcleos de tempo real, foram obtidos resultados muito promissores para os modelos semi-empíricos propostos.
A simulated environment is the less expensive and fastest way of evaluating the relative merits of different control schemes for a given hydraulic system. A new technique, called hardware-in-the-loop simulation (HILS), is emerging to test hardware controllers in virtual environments simulated in real time. This thesis proposes a methodology to organize model libraries, a set of semiempirical hybrid models for hydraulic components and a platform for hardwarein- the-loop simulation experiments. The methodology holds in the association of a new object oriented modelling language, called Modelica, to describe model structure, with the Statecharts graphical formalism to describe its hybrid behaviour. In order to implement the proposed methodology, a new Statecharts library in Modelica was developed. Among the proposed hydraulic component models there is a set of new semiempirical models for high performance proportional valves. The developed models use either data sheet or experimental values to fit the model parameters in order to reproduce both static (pressure gain, leakage flow rate and flow gain) and dynamic (frequency response) valve characteristics. An experimental platform was setup to test the developed hybrid models performance in hardware-in-the-loop simulation experiments. The platform is composed by a hydraulic actuated manipulator with a set of sensors, by real time hardware and by a package of software tools for data acquisition and control. Very satisfactory results, from a set of HILS experiments performed in different real time kernels were obtained for the semi-empirical models proposed.

Повний текст джерелаNext-generation U.S. Navy destroyers, known as DD(X), will use electric drive motors to meet their propulsion needs instead of the traditional mechanical drives. The use of electric drive motors in naval vessels has spurred the development of high power converters. This thesis examines the feasibility of using an advanced control algorithm known as Sine-triangle Pulse Width Modulation (SPWM) in combination with a Cascaded Multi-Level Converter (CMLC) in order to meet the U.S. Navy's strict requirements. The SPWM control algorithm was designed in Simulink and experimentally tested on a CMLC previously constructed at the Naval Postgraduate School. The controller and converter successfully powered a quarter horsepower three-phase induction motor.
