  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

  4. 3. Control Aid Implementation -Modelling and simulation of triple extruder-

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Karl Langsér; [2023]
    Nyckelord :Machine Learning; Extruder; Modelling; Simulation; Extreme learning machine; Chemical engineering; Technology and Engineering;

    Sammanfattning : In the production of their High Voltage Direct Current Cables (HVDC) and High Voltage Alternating Current Cables (HVAC), NKT uses triple extruders to create layers of insulation and semi-conduction. A model to predict the effect of extruder inputs on the cable’s insulation and semi-conducting layers has been created and trained to predict the extruder in discrete time. LÄS MER

    Sammanfattning : Energy efficiency in electric machines is both environmentally and economically important. Water pumps with an integrated Variable Frequency Drive (VFD) and a Permanent Magnet Synchronous Machine (PMSM) have challenged the status quo of the Induction Machine (IM) for water pumps. LÄS MER

  7. 5. Optimal Knock Sensor Spatial Locations of In-line Combustion Engines : A Case Study of Scania Engines

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Hassan Hussein; [2023]
    Nyckelord :;

    Sammanfattning : In recent years, there has been a growing interest in utilizing knock sensors as a diagnostic tool for providing valuable insights into the combustion process. These sensors have demonstrated their potential to offer information regarding crucial parameters such as the start of combustion, heat release rate, misfire events, and valve events. LÄS MER
