An optimal control method based on the minimum energy of the vibration system is proposed for piezoe lectric damping control of the reinforced aircraft plate. Subsequently, the dynamic equations of the piezoelectric damping reinforced plate system and the state space equations are derived. The method to determine the weight matrix of the system is presented based on the minimum energy of the vibration system. In order to obtain the op timal controller, the control parameters of the feedback controller are obtained by using the optimal method. A piezoelectric vibration optimal control experiment platform is designed to control the vibration of reinforced aircraft plate. The experimental results show that the method has good control performances.
