  1. 1. FPGA Based Control of Multiple Electric Machines for Marine Propulsion Systems

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Simon Weideskog; [2024]
    Nyckelord :FPGA; Field Oriented Control; BLDC; SVPWM; SMO; Electric Drives; Electric Machines; Sliding Mode Observer; Marine Propulsion; Multiple Machines; Boat Motor; Fältorienterad styrning; marin framdrivning; elektriska drivsystem; elmaskiner; flertal maskiner; båtmotor;

    Sammanfattning : This master thesis addresses the control of electric propulsion motors in a marine context. The focus lies mainly on the implementation of field oriented control (FOC) in a field programmable gate array (FPGA). The hypothesis is that FPGAs provide performance advantages over microcontroller-based control solutions by enabling parallel processing. LÄS MER

  3. 2. Development of a Compact Drive System for Total Artificial Heart

    Master-uppsats, KTH/Medicinteknik och hälsosystem

    Sammanfattning : Over eight decades of research into total artificial hearts (TAHs) has significantly contributed  to saving end-stage heart failure patients. However, at the current stage of development TAHs have several limitations, one of them being their bulkiness. LÄS MER

  4. 3. Reaction Wheel Control System for a Self-balancing Bike : Reaction wheel based control mechanism for a small scale prototype bike

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Reman Soryani; [2023]
    Nyckelord :Mechatronics; Control Theory; Reaction Wheel; PID Controller; Robotics; Mekatronik; Reglerteknik; Mekanik; PID reglering; Robotik;

    Sammanfattning : In this thesis, the design of a self balancing prototype bike with a reaction wheel as balancing mechanism will be investigated. Bikes are inherently unstable systems, that dynamically resemble an inverted pendulum at a stand still. LÄS MER

  5. 4. Analys och minskning av effektförlusterna i en borstlös likströmsmotor med vektorstyrning

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Lider Xavier Garcia Parrales; [2023]
    Nyckelord :Effektförluster Borstlös likströmsmotor BLDC Vectorstyrning Field-oriented Control FOC Blockkommutering Block commutation MTPA; Technology and Engineering;

    Sammanfattning : This report addresses power losses in an electric motor arising from various sources. The choice of motor control strategy can decrease efficiency if not implemented correctly or if the motor model in the control loop is overly simplified. LÄS MER

  7. 5. Comparative Study of Genetic Algorithm Optimized FO-PID and LQR Control Strategies Applied to a Piston Pump in a Volume Calibration System

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Yaman Deif; [2023]
    Nyckelord :FOPID; LQR; GA; Servo Piston Pump; BLDC; Control Comparison; System Modeling; Volume Measuring.; FOPID; LQR; GA; Servo Piston Pump; BLDC; Styrjämförelse; Systemmodellering; Volymmätning.;

    Sammanfattning : One of the key responsibilities of Getinge's ventilators is to deliver accurate gas volumes to patients. To ensure this precision, specially designed rigid steel tanks are utilized to evaluate the performance and precision of the ventilators in providing exact air volume. LÄS MER
