摘　　要：While positive feedback exists in an active vibration control system, it may cause instability of the whole system. To solve this problem, a feedforward adaptive controller is proposed based on the Fihered-U recursive least square （FURLS） algorithm. Algorithm development process is presented in this paper. Real time active vibration control experimental tests were done. The experiment resuits show that the active control algorithm proposed in this paper has good control performance for both narrow band disturbances and broad band disturbances.While positive feedback exists in an active vibration control system,it may cause instability of the whole system.To solve this problem,a feedforward adaptive controller is proposed based on the Filtered-U recursive least square(FURLS) algorithm.Algorithm development process is presented in this paper.Real time active vibration control experimental tests were done.The experiment results show that the active control algorithm proposed in this paper has good control performance for both narrow band disturbances and broad band disturbances.
