摘要： The finite element dynamic model for integrated structures containing distributed piezoelectric sensors and actuators (S/As )is formulated with a new piezoelectric plate bending element in this paper.The problem of active vibration control and suppression of integrated structures is investigated under constant gain negative velocity feedback control law.A general method for active vibration control and suppression of integrated structures is presented.Finally, numerical example is given to illustrate the validity of the method proposed in this paper.
