Active vibration control and suppression for integrated structures

The finite element dynamic model for integrated structures containing distr ibuted piezoelectric sensors and actuators ( S/As ) is formulated with a ne w 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 metho d for active vibration control and suppression of integrated structures is presented. Finally, numerical example is given to illustrate the validity o f the method proposed in this paper.
