Abstract

A new approach of vibration cancellation in magnetic bearing systems is presented. It is a feed-forward controller approach. The problem is formulated by designing an adaptive filter type of FIR filter. The reason behind employing the FIR filters is that they are inherently stable due to their structure. The FIR filters use forward paths only. A Recursive Least Square algorithm is used for updating filter coefficients. The experimental results show that the proposed method is effective for vibration cancellation in magnetic bearing systems.
