1. FPGA Based Control of Multiple Electric Machines for Marine Propulsion Systems
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)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
2. Development of a Compact Drive System for Total Artificial Heart
Master-uppsats, KTH/Medicinteknik och hälsosystemSammanfattning : 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
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)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
4. Analys och minskning av effektförlusterna i en borstlös likströmsmotor med vektorstyrning
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automationSammanfattning : 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
5. Electric Load Driven Longboard
Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : This bachelor’s thesis aims to show an extensive overview of all the parts that build up an electric load driven longboard and see if a load controlled longboard can be seen as a safe, comfortable and convenient alternative to the more common remote controlled longboard. The thesis will also answer how weight can be measured on a longboard in the most effective way, what the most comfortable riding technique is and what a good motor-battery configuration to be able to travel at 30 km/h and 10 km would be.
