    Sammanfattning : A Switched Reluctance Machine (SRM) is evaluated in terms of torque quality and speed ripple for a particular pump application. The aim is to give BorgWarner insight into the control methodology and possible applications for a Switched Reluctance Machine. LÄS MER

  3. 2. Optimal torque split strategy for BEV powertrain considering thermal effects

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

    Författare :Dhananjay Yadav; [2021]
    Nyckelord :Optimal torque-split control strategy; battery electric vehicles; thermal model of electric machines; system identification; model order reduction; co-simulation.; Optimal vridmomentsdelningsstyrningsstrategi; batteridrivna fordon; termiska modeller av elektriska maskiner; systemidentifiering; minskning av modellorder; samsimulering.;

    Sammanfattning : A common architecture for electric vehicles is to have two electric machines one each on the front and rear axle. Despite the redundancy, this configuration ensures performance. Being energy efficient is equally important for electric vehicles to deliver a sufficiently high range. LÄS MER

  4. 3. The Energy Efficiency Model of a DC Motor for the Control of HEVs

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

  7. 5. Crank Angle Based Virtual Cylinder Pressure Sensor in Heavy-Duty Engine Application

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Mikael Gustafsson; [2015]
    Nyckelord :CLCC; in-cylinder pressure; cylinder separation; torsion.;

    Sammanfattning : The in-cylinder pressure is an important signal that gives information about the combustion process. To further improve engine performance, this information can be used as a feedback signal in a control system. Usually a pressure sensor is mounted in the cylinder to extract this information. LÄS MER
