Abstract

We propose a method to obtain the compensation signal to suppress the vibration of the motor frame by the repetitive control installing an online Fourier transformer and utilizing an acceleration sensor attached to the motor frame or an acoustic signal detected by a microphone placed close to the frame. The sensor is used only for the acquisition of the feedforward compensation data. Moreover, we present a new method of the feedforward compensation control adapting to change of operating point of the motor. Effectiveness of the proposed method is confirmed by the experimental results
