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

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Simon Weideskog; [2024]
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 2. Development of an Investigation Method to Analyse Effect of Laser Cutting on Iron Losses in an Electric Machine

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Rishabh Raj; [2022]
    Keywords : Electrical machine; iron losses; laser cutting; loss models; manufacturing defects; single sheet tester; Elektrisk maskin; järnförluster; laserskärning; förlustmodeller; tillverkningsfel; enplåtsprovare;

    Abstract : In this fast pace world, climate change is one of the primary concerns worldwide. The world is racing towards reducing CO2 emissions by focusing on decreasing energy consumption. Electric motors capture about two-third of the industrial energy consumption, of which the most growing sector is electrical vehicles. READ MORE

  4. 3. Predictive Deceleration Control

    University essay from KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Author : Felix Collin; [2022]
    Keywords : Predictive control; Map information; Feedforward control; Deceleration control; Prediktiv reglering; Information från kartor; Framkopplingsreglering; Retardationsreglering;

    Abstract : For vehicles equipped with electric motors there exist a possibility to recuperate energy during deceleration. This master’s thesis presents a driver support function, a Predictive Deceleration Control (PDC), that warns the driver when to release the accelerator pedal. READ MORE

  5. 4. Energy Consumption Optimization of Electric Vehicles

    University essay from KTH/Fordonsdynamik

    Author : Zhifeng Sun; [2021]
    Keywords : Electric vehicle; torque allocation; regenerative braking; LQR; rear axle steering; Elfordon; tilldelning av vridmoment; regenerativa bromsstrategier; LQR; bakaxelstyrning;

    Abstract : This master thesis report has studied several methods to improve the energy consumption of an electric vehicle equipped with two permanent magnet synchronous motors. Two driving torque distribution maps are developed based on efficiency map and load transfer, respectively. The drive torque distribution map based on the efficiency map shows up to 8. READ MORE

  6. 5. Modelling of electromechanical motors for turret and barrel control in main battle tanks

    University essay from KTH/Fordonsdynamik

    Author : Arvid Carlstedt; [2021]
    Keywords : Mechanics; Mechatronics; Vehicle Technology; Mekanik; Mekatronik; Fordonsteknik;

    Abstract : In this master thesis the dynamics of a modern main battle tank's turret traverse and gun elevation have been modelled. The models of dynamic motion have been coupled to two different types of electric motors, namely a direct-current motor and an induction motor. READ MORE
