Current Compensation Signal in Suppression Control for frame vibration of PMSM by Sensorless Control

Abstract

It is well known that the frame vibration of the PMSM occurs. The authors have suggested a suppression frame vibration method using Fourier transform and repetitive control. The method requires an acceleration sensor and a position sensor. However, the use of such a sensor is not desired from a cost point of view. Therefore, in this paper, we propose a frame vibration suppression method with no sensor. The effectiveness of the proposed method is illustrated thorough some experiments.
