摘要：
This paper presents experiment results of vibration control for flexible beams. Smart material Such as piezoelectric plastic PVDF is used,is sensor and actuator. The linear quadratic regulator (LQR) algorithm is employed for the controller design. The controller is implemented on the basis a floating-point digital signal processor (DSP) TI-C32. The digital board is designed to contain the DSP and the A/D and D/A converter, From analytical and experimental results, this control system has a fine performance of vibration control effect for flexible structure. Experiment also demonstrates the capacity of smart material being used as sensors and actuators for vibration suppression.
