  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. Sensorless Field-Oriented Control and Position Estimation

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

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

    Sammanfattning : 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. LÄS MER

  4. 3. Sensorless Hybrid Field-Oriented Control Two-Phase Stepper Motor Driver

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Emil Lydell; [2023]
    Nyckelord :Stepper motor; Field-Oriented Control; FOC; Driver; Two-Phase; 2-Phase;

    Sammanfattning : Hybrid stepper motors are small electrical motors with high torque production, compared with other electrical motors of the same size. Hybrid stepper motors are reliable in open-loop systems, in Sinusoidal mode, but with a drawback of high power consumption. LÄS MER

  5. 4. A designer-driven approach to procedural generation tools for level design

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

    Författare :Max Truedsson; [2023]
    Nyckelord :Master Thesis; Game development; Game Design; Procedural generation; PCG; Level creation; Art Tool; 3d Environment design; Master Examensarbete; Spelutveckling; Speldesign; Procedurell generering; PCG; Spelbana Konstruktion; Konst verktyg; 3d miljö design;

    Sammanfattning : Game development is a multifaceted field that involves both traditional software practices and creative work. It is characterized by its iterative and time-consuming process where prototypes are created and then evaluated. This is especially true for creating 3D environments, where it is difficult to evaluate the quality before it is completed. LÄS MER

    Sammanfattning : AbstractIs Ukraine the battlefield of external powers? The 2014 conflict in Ukraine was characterized by multiple media narratives, which shaped the portrayal and understanding of the conflict. Was it a geographical conflict between Ukraine and Russia, or a proxy war between the West and Russia? Control of the information arena is central to contemporary warfare, which marks research on the conflict in Ukraine. LÄS MER
