CONTROL OF PIEZOELECTRIC SMART STRUCTURES

This paper describes the controller design for multi layered piezoelectric structures. Piezoelectric materials have a big advantage, from control point of view, of making it easy to adjust the actuators and sensors to the special structural application that is to be controlled. The paper demonstrates that an appropriate spatial shaping of the surface electrodes of the piezoelectric actuator and sensor layers simplifies the control synthesis task to a great deal.
