파라미터 동정과 순시무효전력을 이용한 IPMSM 센서리스 제어

초록

IPMSM is necessary to use the accurate values of the inductance for the precise torque control, because of using the reluctance torque of the IPM. This paper presents method to uses the hysteresis loop inclination of the flux and current measured by applying the positive and negative voltage pulse alternately on the each-axis. Moreover, presents algorithm for speed sensorless control based on parameter identification and instantaneous reactive power.
