Though the filtered X least mean square(FXLMS) control algorithm has dr awn wide attention in the field of active structure vibration control, the algor ithm has defects in practical application that the reference signal can not be e xtracted from the vibration structure directly. This paper proposed a control st ructure and algorithm that could extract the reference signal directly from the structure, with the basic thought that an estimated value of the original excita tion signal obtained from the system error signal is regarded as the reference s ignal of adaptive filter in order to achieve correlation with external excitatio n signal. Based on the simulation analysis by MATLBA, an active vibration measur ement and control platform for a piezoelectric flexible beam is established. Wit h the constructed model structure and the experimental platform, the experiment of the proposed algorithm is conducted. The experimental results show that the c ontrol algorithm not only realizes the reference signal selfextraction from th e vibratory structure, but also has a faster convergence speed and better control performance.
