Paper Abstract

Smart structure has become an increasingly common term describing a structure embedded or bonded with a large number of lightweight active electro-mechanical sensors and actuators. In this paper, we consider the modeling and control issues related to smart structures bonded with piezoelectric sensors and actuators from the passivity viewpoint. We show that when a piezoelectric patch is used both as an actuator and a sensor, the mapping from the voltage input to current output is passive, which implies that any strictly passive feedback controllers are stabilizing. Issues related to the design of the passive feedback controller with performance optimization and controller order reduction are investigated.
