The present paper describes the vibration control experiment of composite plates with bonded piezoelectric sensor and actuator. The system is modeled as two degree-of-freedom system using modal coordinates and the system paramenters are obeained from vibration tests. Kalman filter is adopted for extracting modal coordinates from sensor signal, and control algorithms applied to the system are Linear Quadratic Gaussian(LQG) control, Bang-Bang Control(BBC), Negative Velocity Feedback(NVF), Proportional-Derivative Control(PDC). From observation of the spillover and control performance, it is concluded that a higher order control algorithm such as LQG rather than BBC, NVF, PDC is suitable for efficient simultaneous control of both bending and twisting modes of composite plates.
