Vibration control of beamplates with bonded piezoelectric sensors and actuators
This paper studies vibration control of beamplates with bonded piezoelectric sensors and actuators. Basic equations for piezoelectric sensors and actuators are presented. The equation of motion for a beamplate structure bonded with pairs of piezoelectric sensors or actuators is derived by using the Hamiltons 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.
