Sensorless control of Switched Reluctance Generator using Instantaneous inductance

순시 인덕턴스를 이용한 SRG의 센서리스 제어

Switched reluctance generators(SRGs) attract much attention in the generator because of high efficiency, simplicity, and ruggedness. They require rotor position information In determine the turn-on and turn-off angle, but the rotor position sensor is less tolerant of extreme environmental conditions, such as high temperature or dust, so the position sensor is limited and undesirable. This paper describes a new approach to estimate the rotor position from the measured terminal voltages and currents of the SRG. The proposed method is based on the instantaneous inductance of the SRG. The proposed method is verified by computer simulations and experiments.
