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

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.
