This paper introduces the control of vibration attenuation of flexible structures in the field of high technology such as aviation and aerospace. The emerging intelligent composite structure technology and its application prospect in the early 1990s. A mathematical model of vibration damping control system for a composite piezoelectric composite laminate windsurfing panel with application background is given and the output / input equation of the piezoelectric sensor / exciter is derived. The numerical simulation of the optimal control algorithm is carried out. The results show that the control effect is significant.
