Variable angle adjustable-high speed control with PI for SRM

This paper presents a new approach to control the turn-off angle θ_off used to excite the Switched Reluctance Motor (SRM) used in electric vehicles (EV). The controller selects the turn-off angle which will improve the performance of the electric drive system with turn-on angle constant. This control scheme consisting of classical current controller and speed controller depend on lookup table to choose the best result from it. The turn-on angle of the main inverter switches is fixed at 0° and the turn-off angle is variable depending on the reference speed and PI current controller. The whole system including motor, inverter and control unit are modeled in Simulink to demonstrate the operation of the system.
