  1. 1. Evaluation of OPAL-RT Simulator through Simulation of Microgrid with High Penetration of DER

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Anton Grönberg; [2024]
    Nyckelord :Real-Time simulation; Power System Simulation; OPAL; DER;

    Sammanfattning : This thesis was written in collaboration with the department of electrical engineering at Uppsala University. It evaluates and tests the potentials and limitations of using the OPAL-RT simulator as a tool for designing and developing control strategies used in microgrids with a high penetration of distributed energy resources.

  3. 2. 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

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

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Arvid Linder; [2024]
    Nyckelord :MPC; Model predictive control; quadcopter; control system;

    Sammanfattning : 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. LÄS MER

  5. 4. BIDRAGSBROTTSLIGHETEN I MALMÖ

    Kandidat-uppsats, Malmö universitet/Institutionen för kriminologi (KR)

    Författare :Amanda Engstrand; Emma Andersson; [2023]
    Nyckelord :Keywords: Crime development; Factors; Situational Action theory; Social welfare crime; Strain theory; Nyckelord: Bidragsbrott; brottsutveckling; faktorer; Situationell handlingsteori; Strainteorin;

    Sammanfattning : Denna studie undersöker bidragsbrottsligheten i Malmö och dess utveckling. Utifrån en kvantitativ ansats med tvärsnittsdesign syftar studien till att belysa utvecklingen av bidragsbrott samt hitta bidragande faktorer till utvecklingsförloppet. LÄS MER

  7. 5. 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
