英文摘要：

According to the output characteristics of control system,a fuzzy controller is used to correct the control law of learning controller in real-time to achieve the dynamic learning process. A fuzzy self- learning control （FSLC） algorithm for piezoelectric smart structure vibration control is presented by the combination of fuzzy logic control and learning control. Piezoelectric actuator/sensor and host structure are modeled by the three-dimension eight-node coupled element （SolidS） and solid element （Solid45） re- spectively. The finite element program for piezoelectric smart structure vibration control analysis has been compiled by ANSYS parameter language. It is proved that the fuzzy self-learning control （FSLC） method can effectively control the vibration of piezoelectric smart structures by numerical simulation, and speed up the convergence of self-learning control. The fuzzy self-learning control has better control results.
