Active vibration control of a flexible plate structure with a rigid base is studied. The vibration mathematical model of a rigid-flexible coupling system with a rigid rotating body and a two-dimensional flexible plate is established. The state equation, the sensing equation and the feedback control equation of the system are obtained. According to the principle of output feedback control, The feedback gain matrix is obtained. Based on this, experiments are carried out. The experimental results prove the rationality and effectiveness of the theoretical research.
