Simple analytical solution for active vibration control of intelligent composite and sandwich plates

Abstract

A simple analytical formulation of laminated composite plates with integrated piezoelectric layer, used as sensor and actuators for the vibration suppression of intelligent composite and sandwich plates is presented. The first order shear deformation theory is employed to account for the transverse shear deformation. The equations are transformed into the state space form and solved by the linear quadratic regulator (LQR) based control algorithm. The effect of the state and control parameters on the system response is studied. The effect of the thickness ratio of the intelligent plate is also investigated.
