  3. 2. 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

  4. 3. Real-Time Certified MPC for a Nano Quadcopter

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Arvid Linder; [2024]
    Keywords : MPC; Model predictive control; quadcopter; control system;

    Abstract : There is a constant demand to use more advanced control methods in a wider field of applications. Model Predictive Control (MPC) is one such control method, based on recurrently solving an optimization problem for determining the optimal control signal. READ MORE

  5. 4. Sensorless Field-Oriented Control and Position Estimation

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Roberts Bitenieks; Lars Brander; [2023]
    Keywords : Sensorless rotor position estimation; High-frequency injection; Technology and Engineering;

    Abstract : This master's thesis investigates the feasibility of implementing field-oriented control for a BLDC motor without relying on a position sensor from a standstill up to 400 rad/s. To achieve this objective, various approaches were used at standstill and high speeds. READ MORE

  6. 5. The Factors Associated with stress among nursing students in clinical practice

    University essay from Högskolan i Gävle/Avdelningen för vårdvetenskap

    Author : Yuyang Jia; Jiahong Wang; [2023]
    Keywords : ;

    Abstract : Background: Nursing trainees move from teaching to the clinic, which is a change in identity with generally high levels of stress due to a variety of reasons. Currently, there is no research for the time being examining the stress-related factors of clinical practice nursing students of Lishui University. READ MORE
