Abstract :
To decouple strong secondary saliencies in sensorless AC drives, a repetitive control method in an angle domain is proposed. This method regards secondary saliencies as periodic disturbances relative to electrical angle and generates the same saliencies to compensate them. The proposed method is easy to implement and proved effective by experiments.
