Dissipativity Based Control of Plate Vibrations by Piezoelectric Sensors and Actuators

Description

Piezoelectric devices represent an important new group of actuators and sensors for active vibration control systems. Indeed, this technology allows to construct spatially distributed devices. A mathematical model of a multilayered piezeoelectric plate, which takes hysteresis and polarization of the piezoelectric laminae into account, is presented. Passive control for Lagrangian systems is used to derive a class of stabilizing control laws, which are based on the collocation of sensor and actuators. Therefore, the design of the spatial distribution of the sensors/actuators is considered as a part of the controller synthesis.
