Vibration control of beam-plates with bonded piezoelectric sensors and actuators
This paper studies vibration control of beam-plates with bonded piezoelectric sensors and actuators. Basic equations for piezoelectric sensors and actuators are presented. The equation of motion for a beam-plate structure bonded with pairs of piezoelectric sensors or actuators is derived by using the Hamilton's principle, and a finite element method is used for the analysis. A control algorithm based on Lyapunov energy function is studied. Numerical results are presented for illustrative purposes. (C) 1999 Civil-Comp Ltd and Elsevier Science Ltd. All rights reserved.
