【Abstract】 A method for active vibration control of flexible structure using piezoelectric sensors and actuators, based on neural network, is proposed. The principle of neural network control is described, control algorithm is derived, and the control system is presented. Finally the experiments on vibration control of a flexible beam, excited by sinusoidal and pseudorandom signals, are performed, and experimental results are presented to verify the proposed method.更多还原
