Streszczenie:
While substantial research has examined the control of Information systems (IS) projects, most studies In this area have only examined how one controller manages a single group of controllees. However, many IS projects, especially enterprise systems projects (often initiated by an organization's corporate headquarters, and involving business unit users and consultants), have multiple stakeholders. The corporate headquarters (the project's principal controller) must simultaneously ensure that the various stakeholders are aligned with the project's goals despite their diverse motivations, and that the stakeholders collaborate with each other to achieve project success. Behavior control theory argues that the controller enacts a control portfolio of formal and Informal controls. However, the presence of multiple controllee groups increases the complexity of vertical controller- controllee relationships, the salience of controllee-controllee relationships, and the interaction between these vertical and horizontal relationships. We therefore examined the creation and evolution of the control portfolio In a multi-stakeholder project over a period of 14 months. We found that (1) the principal controller did enact separate controls for the user and consultant groups; (2) there was more than one controller - the principal controller co-existed with subordinate controllers; and (3) controls enacted by the subordinate controllers and other controllees that cut across stakeholder groups required the support of the principal controller.

<span lang="EN-US">This work presented two fuzzy logic (FL) schemes for speed-controlled brushless DC motors. The first controller is a Type 1 FL controller (T1FLC), whereas the second controller is an interval Type 2 FL controller (IT2FLC). The two proposed controllers were compared in terms of system dynamics and performance. For a fair comparison, the same type and number of membership functions were used for both controllers. The effectiveness of the structures of the two FL controllers was verified through simulation in MATLAB/SIMULINK environment. Simulation result showed that IT2FLC exhibited better performance than T1FLC.</span>

Abstract In this work, diabetic glucose concentration level control under disturbing meal has been controlled using two set of advanced controllers. The first set is sliding mode controllers (classical and integral) and the second set is represented by optimal LQR controllers (classical and Min-, ax). Due to their characteristic features of disturbance rejection, both integral sliding mode controller and LQR Minmax controller are dedicated here for comparison. The Bergman minimal mathematical model was used to represent the dynamic behavior of a diabetic patient’s blood glucose concentration to the insulin injection. Simulations based on Matlab/Simulink, were performed to verify the performance of each controller. In spite that Min-max optimal controller gave better disturbance rejection capability than classical optimal controller, classical sliding mode controller could outperform Min-max controller. However, it has been shown that integral sliding mode controller is the best of all in terms of disturbance rejection capability. Key words: Optimal LQR control, Optimalminimax control, Sliding mode control, Integral sliding mode control.

Streszczenie:
This paper presents a novel tetra-level dynamic decomposition-based control approach for coordinated operation of electric vehicles in multimicrogrids, which is comprehensive, generic, modular, and secure in nature, to maximize the utilization of renewable energy sources, while meeting the load demands with the resources available. There are a number of microgrids that are connected to the grid. Each microgrid consists of a number of renewable energy sources, energy storage systems, non-renewable energy sources, electric vehicles, and loads. Each distributed energy source or load is controlled by a microsource controller. All microsource controllers with a similar nature are controlled by a unit controller, and all the unit controllers in a microgrid are controlled by a microgrid controller. There is a single multimicrogrid controller at the top. The proposed control scheme was verified through simulation-based case studies.

Streszczenie:
Uniform approach to selection of PID settings for heading and path tracking controllers that create a cascade control system for ship autopilot is presented. Uniformity of the design follows from observation that for each of the controllers the controlled plant looks like an integrator with time constant. In case of the heading controller, the plant is represented by the known Nomoto model. Due to elimination of the plant time constant by the controller, each of the closed loop systems becomes of 2nd order. One assumes that such system should have a double time constant, different in a prescribed ratio from time constant of the controlled plant. It is shown that the heading controller designed in this way suppresses disturbances better than the controller with standard settings.

The choice of a vehicle speed controller for a permanent magnet synchronous driven battery electric vehicle (BEV), integrated with a regenerative braking system (RBS), plays a pertinent role in how far a vehicle can travel. While many studies have implemented varied control strategies, the proportional-integral (PI) based controller is predominately studied and practically used. Generally, the performance of PI controller compared to Modeled Predictive Controller; Reference Tracking Signal Controller Based on Generated Polynomial and Reference Tracking Signal Controller Based on Controlled Polynomial in a permanent magnet synchronous motor (PMSM) driven battery electric vehicle integrated with RBS speed control based on field-oriented control mechanism is lacking. In order to address that shortcoming, this paper aims to investigate the performance of a PI controller compared to generalized predictive controllers based on the difference between a reference speed and a controlled speed of the battery electric vehicle. The performance for each controller considered was evaluated in terms of the state of charge (SOC), R^2, slip ratio, minimum error metrics, and peak speed using real-time driving scenario factoring braking, throttling, wind speed, and cruise effects for 15 s. The results show that the PI controller outperforms the other controllers on most metrics. Except for the peak SOC, slip ratio, and peak speed, the Reference Tracking Signal Controller Based on Generated Polynomial seems to be better, although with a drawback of the highest error metrics. Generally, all the controllers yielded excellent regenerative braking effects in SOC and effective control of the speed trajectory.

The robot controller plays an important role in controlling the robot. The controller mainly aims to eliminate or suppress the influence of uncertain factors on the control robot. Furthermore, there are many types of controllers, and different types of controllers have different features. To explore the differences between controllers of the same category, this article studies some controllers from basic controllers and advanced controllers. This article conducts the benchmarking of the selected controller through pre-set tests. The test task is the most commonly used pick and place. Furthermore, to complete the robustness test, a task of external force interference is also set to observe whether the controller can control the robot arm to return to a normal state. Subsequently, the accuracy, control efficiency, jitter and robustness of the robot arm controlled by the controller are analyzed by comparing the Position and Effort data. Finally, some future works of the benchmarking and reasonable improvement methods are discussed.

In this study, the actuator, which converts circular motion to linear motion, is controlled with a smart hybrid controller. The model includes the analysis of electrical and mechanical parts. The controller, on the other hand, has a design methodology that cleverly blends classical PID (Proportional Integral Derivative) and fuzzy controllers. In this design methodology, classical PID and fuzzy controller have an error parameter dependent blending mechanism. In order to compare the performance of the hybrid controller, the coefficients of the classical PI and PID controllers were obtained by tuning and the coefficients with the best response were used. For performance comparison of conventional controllers and hybrid controllers; rise time, settling time, maximum overshoot and common performance indices values are used. The hybrid controller showed higher performance in terms of maximum overshoot, settling time, rising time and performance indices. The potential benefits of using a hybrid controller for the control of linear electric actuators were demonstrated by the fact that it performed better than conventional PID controllers on the majority of evaluation criteria.

Den datainsamlingsmetod som användes var personliga intervjuer utifrån ett selektivt urval med 7 respondenter från Scania. Analysmetoden bestod i att den teoretiska referensramen jämfördes med det som framkom vid datainsamlingen. Slutsatserna består av följande delar: Det är tydligt att det finns ett behov av en definition av controllerrollen, enligt såväl teori som empiri. Controllerns plats organisatorisk sett på Scania stämmer inte med synen i den teoretiska referensramen Vissa risker är förknippade med den organisationsform som valts, bl.a. är det av stor vikt att controllerns oberoende säkras Då delade meningar råder kring vilka arbetsmoment som en controller bör utföra och syftet med arbetet bör detta klargöras En controller bör stanna på sin tjänst under flera år för att nytta ska kunna tillföras verksamheten, dessutom är det viktigt att ha en mix i controllerpopulationen Vid en nyrekrytering bör en rad kvalifikationer och egenskaper bejakas hos de personer som är aktuella.

Bakgrund och problem: Till följd av samhällets och företags ökade medvetenhet avseende hållbarhet har det banat ny väg för idéer om vad som utgör styrinformation i företag. Hållbarhet har blivit allt mer integrerat inom företag vilket har förändrat dess interna processer. Förändringar i de interna processerna har lett till att det inte enbart handlar om finansiell information längre, utan nu även hållbarhetsinformation. Som följd av detta har arbetsuppgifter omformats och utmanats vilket har ändrat controllerns arbete. Hållbarhet har fått ett sådant stort fokus att det har tillkommit en ny roll vid namn hållbarhetscontroller. Vad en hållbarhetscontroller är har inte diskuterats tidigare i litteraturen, vilket följande studie ämnar att göra.  Syfte: Syftet med denna studie är att bidra med kunskap om vad en hållbarhetscontroller är och gör i en organisation. Detta kommer att undersökas genom att utreda vilka arbetsuppgifter och kunskaper en hållbarhetscontroller utför och besitter för att ytterligare förstå sig på rollen.  Metod: Studien utgår från en kvalitativ metod som omfattar en explorativ undersökning. Den empiriska datainsamlingen gjordes genom semistrukturerade intervjuer, som har hållits med åtta hållbarhetscontrollers samt en hållbarhetsstrateg. Vidare har det använts elektroniska källor och dokument i form av arbetsannonser. Det teoretiska materialet är hämtat från vetenskaplig litteratur och det utgörs av controllerns bakgrund, arbetsuppgifter, roll, kunskaper samt hållbarhet. Slutsats: Utifrån studien anses hållbarhetscontrollers vara en kombination av en traditionell controller och business controller, därmed en hybrid. Detta då den arbetar med verksamhetens hållbarhetsredovisning men också som en affärspartner som bistår ledningen med underlag. Hållbarhetscontrollers fundamentala roll är hållbarhetsredovisningen vilket kopplas till en kamrer. Rollen analytiker var den roll som framkom tydligast i hållbarhetscontrollern och därmed konstaterades vara den viktigaste. Rollen som pedagog ser vi idag vara mindre då hållbarhet har blivit så pass integrerat, däremot innebär rollen idag att agera mer som en coach till följd av det stora fokuset på hållbarhet. Studien kunde därmed se att rollen har skiftat från att vara en traditionell “bean counter” till en affärspartner till organisationen. Hållbarhetscontrollern arbetar likt en controller där det som skiljer sig åt är att fokuset ligger på sociala och miljömässiga aspekter. Till följd av detta innebär det att kunskap kring hållbarhet och dess riktlinjer och ramverk var den viktigaste kunskapen för att besitta rollen. Vidare behövs god kunskap för verksamheten och ett innovativt tänkande vilket är viktigt för att ständigt kunna utveckla hållbarhetsarbetet och applicera nya riktlinjer i verksamhetens kontext. Antalet hållbarhetscontrollers på marknaden ökar gradvis och med hjälp av denna studie kommer fler företag få en inblick i varför företag väljer att ha en hållbarhetscontroller i deras verksamhet.
Background and problem discussion: As a result of the company's and society's growing awareness of sustainability, it has established new ideas about what constitutes control information in companies. Increasingly, sustainability has been integrated within the organization, and the company's internal processes have changed. The change in the internal processes has developed it to be more than just financial information and sustainable information. Tasks have thus been reshaped and challenged, which has also changed the controller's work. Sustainability has received such a significant focus that a new role has been created, called a sustainability controller. A sustainability controller has not been discussed before in literature, which is the following study's intentions. Purpose: This study aims to contribute knowledge about what a sustainability controller is and does in an organization. This matter is investigated on what tasks and knowledge a sustainability controller performs and possesses to understand the role further. Methodology: The study is based on a qualitative method that includes an exploratory study. The empirical data collection was done through semi-structured interviews, which have been held with eight sustainability controllers and a sustainability strategist—furthermore, utilizing electronic sources and documents in the form of job advertisements. The theoretical material is obtained from the scientific literature on background checks, tasks, roles, knowledge, and sustainability. Conclusion: According to this study, sustainability controllers are considered a hybrid of traditional controllers and business controllers. It works with a business's sustainability reporting and being a business partner that assists the management with data. The fundamental role of sustainability controllers is the sustainability report, which is linked to a bean counter. The role analyst emerged most clearly in the sustainability controller and was the most significant. Today's role as an educator is minor as sustainability has become so integrated; however, the role needs to act more as a coach due to the significant focus on sustainability. Thus, the study could see that the role has shifted from being a traditional bean counter to a more business partner to the organization. The sustainability controller works like a controller where what differs is that the focus is on social and environmental aspects. As a result, knowledge about sustainability, the guidelines, and the framework was essential to possess the role. Furthermore, good knowledge is expected for the business and innovative thinking, which is vital to constantly develop sustainability work and apply new guidelines in the business context. The number of sustainability controllers on the market will gradually increase. With the help of this study, more companies will gain insight into why companies choose to have a sustainability controller in their operations.

Con l'espressione `Vibration Control' si intende l'insieme delle tecniche e dei dispositivi che consentono di mitigare in modo rapido, a dabile e preciso le vibrazioni di macchine o strutture, dovute al loro stesso funzionamento o a causa di forze esterne. Nella realizzazione dei sistemi di controllo delle vibrazioni assumono oggi primaria rilevanza sul piano tecnico ed economico l'hardware impiegato. Attuatori elettrici e oleodinamici, dispositivi passivi,sensori, convertitori elettronici e unit a di controllo rappresentano una parte fondamentale di tali sistemi e ne influenzano largamente le prestazioni. Il contributo del singolo componente alle prestazioni complessive del controllo è tuttavia valutato compiutamente solo se ci si pone in un'ottica di sistema, nella quale le mutue interazioni tra componenti elettronici, parti meccaniche e algoritmi di controllo trovano la loro corretta sintesi. Nei sistemi di controllo delle vibrazioni, è decisiva la scelta del `controller'. Scopo del presente lavoro e stato appunto quello di sviluppare un sistema di controllo delle vibrazioni che coniughi le diverse esigenze di precisione, determinismo e elevata velocità di servo-aggiornamento, tipiche di un circuito stampato, alle esigenze di flessibilità ed economicità, tipiche delle soluzioni basate su DSP, e alle elevate capacità di calcolo tipiche di un pc. Per far ciò il ruolo di controller e a dato ad un dispositivo PAC (Programmable Automation Controller) basato su tecnologia FPGA (Field Programmable GateArray) che consente di codifcare, in modo rapido, le funzionalit a richieste al controllo su un dispositivo programmabile di tipo hardware e per questo dalle prestazioni paragonabili a quelle di un circuito stampato. With the expression `Vibration Control' refers to the set of techniques and devices that let you mitigate quickly, reliably and accurately the vibrations of machines or structures, due to themselves operation or due to external forces. In the implementation of vibration control systems today assume pri- mary importance, in the technical and economic terms, the hardware used. Electrical and hydraulic actuators, passive devices, sensors, electronic con- verters and control units are a fundamental part of these systems and they greatly a ects on the performance. In systems of vibration control, is decisive the choice of the controller. The purpose of this work was to develop a system of vibration control which combines the various requirements of precision, determinism and high-speed servo-update, typical of a printed circuit board, the exibility and economy typical of solutions based on DSP, and high computing power of a typical PC. To do this, the role of controller is assigned to a device (PAC programma- ble automation controller) based on technology FPGA (Field Programmable Gate Array) which allows to encode, quickly, the required functionalities to the control, on a programmable hardware device and for this with perfor- mance comparable to that of a printed circuit board.

This diploma work describes how an FPGA is designed to control a CAN controller. It describes the different tools used when working with Actel’s design tools and the sequence of work applied. It gives a short overview of a multiplexer, the CAN bus, an analog/digital-converter and some more information on the actual FPGA. It also brings up the design process of the FPGA, planning, coding, simulating, testing and finally programming the FPGA. The different parts implemented in the FPGA are a shift-register and two state- machines that are connected with each other. They work together to control the SJA1000 CAN controller made by Philips. They also receive data from the analog/digital-converter that they forward onwards to the CAN controller that forward the data on the CAN bus.

Problematization: Financial departments have during the recent years developed due to environmental changes, and so has the controller profession. Controllers are working hard in the shadow of the CFO, together with an unclear definition over their tasks. By shedding light on the controller can their value-creation for the organization be defined. Purpose: The purpose of this research is to examine developments of the controller profession from a Swedish organizational context. Furthermore, this thesis aims to investigate if there is an expansion of the controller professions role, within organizations, that affecting their ability to create value. Methodology: The research has been conducted with a qualitative approach. In this study was 8 interviews performed with controllers in Swedish organizations. This research further examines the controller profession from a general context, in other words, without no specific industry orientation. Findings /conclusions: The findings of this study argue for that there still exist an indistinct definition over the controller profession, thus developments within their role can be confirmed. The traditional view of controllers’ work should therefore be prolonged. Controllers are still just as accountable for financial assignment, the role has however, developed to become involved in most of parts organizations’ businesses and adapted an advisory role. The advancements have made the controller role to a central position with great ability to create value within an organization, yet, to what extend depends on various factors and aspects.

Since a few years, flat screen TVs, such as LCD and plasma, has come to completelydominate the market of televisions. In a SoC solution for digital TVs, severalprocessors are used to obtain a decent image quality. Some of the processorsneed temporal information, which means that whole frames need to be storedin memory, which in turn motivates the use of SDRAM memory. When higherdemands of resolution and image quality arrives, greater pressure is put on theperformance of the SoC memory subsystem, to not become a bottleneck of thesystem.

In this master thesis project, a model of an existing SoC for digital TVs is usedto benchmark and evaluate the performance of an SDRAM memory controllerarchitecture study. The two major features are the ability to reorder transactionsand the compatibility with DDR3. By introducing reordering of transactions, thechoice is given to the memory controller to service memory requests in an orderthat decreases bank conflicts and read/write turn arounds. Measurements showthat a utilization of 86.5 % of the total available bandwidth can be achieved, whichis 18.5 percentage points more, compared to an existing nonreordering memorycontroller developed by NXP.

The project was performed with universal electronics which is based in Karachi Pakistan at PRD Lab. Due to the energy crises the industry is switching to alternative power generators. The main issue with the maintenance of the generator is the constant failure of the controller which has to be imported ,the purpose of this project is to make a cheap efficient Electronic Frequency Controller (EFC) that can be used in almost all kinds of generators. The work was tested on Multisim and then soldered together. To make it functional the frequency generation was converted to voltage which was connected to the controller. The controller was joined with the actuator and the actuator opens the amount of fuel needed to run the generator so that there is a smooth constant voltage. If we have high frequency from the input like a heavy machinery is operational then the actuator will widen its opening and when the frequency is low the actuator will open appropriately. The presentation was a successful one but due to time deadline few minor adjustment could be made to make it more effective as discussed later.

Abstract Smart wheelchairs with semi or fully autonomous functions, can greatly improve the mobility of physically impaired persons. However, most are controlled using inputs that require physical manipulation (e.g. joystick controllers) and for persons with severe physical impairments this method of control can be too demanding. A noninvasive brain-computer interface (BCI) technology-based controller could bridge between the smart wheelchairs users and physically impaired persons with severe conditions. Current BCI controlled wheelchairs rely on detecting steady-state visually evoked potential (SSVEP) responses as these typically have the greatest data transfer rate. However, this method requires the user to focus on a screen for an extended period of time. This causes strain on the user and takes their attention away from their surroundings, which could be dangerous in a scenario that requires navigation around multiple moving objects. The focus of this project is to design a hybrid BCI controller using an electroencephalogram (EEG) headset to detect hand motor imagery (MI) and jaw electromyography (EMG) signals to control a smart wheelchair in conjunction with its semi-autonomous capabilities. A controller of this kind is well-known to have low data transfer rates, and therefore has lower accuracy and longer response times as compared to other controllers. However, a properly structured controller hierarchy between the BCI controller and semi-autonomous system is developed to compensate the limitations of the controller’s accuracy.

Streszczenie:
The dynamic behavior of a Duffing-Holmes oscillator subjected to a Hybrid Position Feedback (HPF) controller is investigated. The so-called hybrid controller is a combination of two controllers, namely, the Negative Position Feedback (NPF), and Positive Position Feedback (PPF) controllers. The controller uses the inertial properties of the structure around its stable positions to achieve large displacements by effectively destabilizing the system using an NPF controller. Once the unstable equilibrium is reached, the system is stabilized to the target stable equilibrium using the PPF controller. This dynamic switch of controllers creates the HPF control concept, which specifically enables the monotonic and controlled transition between the states of bistable systems such as the Duffing-Holmes oscillator. This concept can be implemented to morphing structures such as bistable wings, wind turbine blades, and deployable structures. In this paper, a detailed response type and stability analyses of a Duffing-Holmes oscillator controlled by the HPF controller are presented. First, the response types for the components of the HPF, NPF and PPF controllers are analyzed individually. For the NPF controller, three response types are defined. These are intra-well, single cross-well, and multiple cross-well response types describing the possible responses. For the PPF controller, only two response types are defined. These are stabilized and not-stabilized, since the role of the PPF controller is to generate an attractor to the desired stable equilibrium. Finally, the complete HPF controller is analyzed in terms of response type. In this case, three response types are defined: intra-well, single cross-well and multiple cross-well. The paper summarizes all the response types with detailed analyses, and recommends controller parameters for best control performance.

Abstract This paper presents a new parameters optimization approach for fractional order PID controllers, which uses a satisfactory optimization model. To fulfill different design performance specfications and constrains of systems, the application of multi-criterion satisfactory optimization to fractional control systems is considered. At the same time, the performance of fractional control systems controlled by fractional order controller and integer order controller is discussed. The simulation illustrates the effectiveness of the proposed method and the superiority of the fractional order controller in both time domain and frequency domain.

Abstract Hybrid thermal management systems (TMS) enable faster response to rapid transient heat loads by supplementing heat rejection through a primary heat sink with temporary heat storage in a thermal energy storage (TES) device. The TES is not a passive component; it must be actively controlled by a realtime controller to decide when the TES should be discharged or recharged. While various types of controllers have been developed for hybrid TMS architectures, controllers for hybrid TMS in transient electronics cooling applications have predominantly been demonstrated in simulation environments. One such controller developed previously is a heuristic logic-based controller that leverages a state of charge (SOC) metric and feedback from several thermocouples placed in the fluid loop to manage the operation of the TES. In that prior work, the controller was demonstrated in simulation only; this paper builds on that work by implementing and validating the controller’s performance in an experimental single-phase hybrid TMS testbed. A particular advantage of this controller is its low level of computational complexity, facilitated by its rule-based architecture, which makes it more amenable for industrial use. We present an experimental case study to demonstrate the heuristic controller’s ability to meet two objectives: reduce the peak temperature at the surface of the cold plate below an allowable threshold and manage the SOC so the thermal storage capacity is not depleted.

Several potential energy-savings devices are available for through-the-wall HVAC (heating, ventilation, and air-conditioning) systems but independent test data quantifying their savings are sparse. This field evaluation and demonstration study quantifies the potential energy savings and assesses the impacts on occupants and staff of using a supervisory HVAC controller in the lodging industry. The supervisory controller operates according to the occupancy status of each room in a hotel or motel. The controller is a plug-in device installed between a wall outlet and the room HVAC unit. Preliminary tests in laboratory simulated environmental conditions suggest that energy savings ranging from 50% to 80% are possible in unoccupied lodging rooms employing the controller (Fisher, 1999). The field study objective was to quantify and verify these estimates and to identify impacts on occupant comfort. The controller was developed as a tool for reducing energy consumption and lowering operating costs in the lodging industry. This paper describes results from a field evaluation of the performance of a supervisory HVAC controller. During the test period, the uncontrolled rooms HVAC energy consumption averaged 2632.2 kWh monthly while the controlled rooms HVACs consume an averaged 1684.6 kWh, which equates to the uncontrolled rooms HVAC consuming an averaged of 947.6 kWh (56.3%) more energy than the units in the controlled room monthly. Due to intermittent inoperability of the controllers and other energy loads (controllers controlled approximately 50% of the hotel’s conditioned space), comparison analysis of the energy cost over a three-year period for the entire hotel does not reveal any discrete savings during the test period over prior years.

Streszczenie:
Arbitrarily fast switching or blending among controllers often leads to reduced performance and possible instability. This paper presents a controller interpolation framework for robustly transitioning among controllers with respect to the H∞ norm. The framework leverages a robust controller parameterization, analogous to a Youla parameterization of nominally stabilizing controllers, to greatly simplify the robust controller interpolation problem. In addition, an explicit construction is provided for the robust interpolated controller. A practical example is presented in the form of a robust interpolated controller implemented on an electro-hydraulic test bed.
