Active vibration control of one-dimensional piezoelectric laminates

Marek Pietrzakowski
In the paper a theoretical model of a simply supported three-layer one-dimensional plate with a distributed actuator/sensor pair has been examined. A velocity feedback control is used to achieve active damping of structure. The transfer functions relating the out-of-plane deformation to the actuator voltage input for the system without control loop and for the system with velocity feedback as well as the open-loop transfer function are obtained. The numerical results show the influence of the actuator/sensor location and controler parameters on the modal system response.
