【Abstract】 The multiple actuators and sensors are used to control the vibration of a simple supported panel. The actuators and sensors are connected only by local feedback loops. In the control system, the force actuators and piezoelectric actuators are considered respectively. To reduce whole energy of the structure, the simultaneous perturbation technology is used to schedule the distributed feedback control gains. The computer simulations show that the distributed feedback gains scheduling strategy proposed in this paper is very effective to control of structural vibration.更多还原
