Abstract

In this study out of plane active vibration control of a laminated composite rectangular plate with intermediate LINE SUPPORT coupled with piezoelectric patches on both sides, upper and lower surface of the plate, is presented based on First order shear deformation plate theory (FSDT). Is this study, the piezoelectric patch is used as a sensor. In the relation of piezoelectric, electrical potential in the transverse direction is earned by satisfying electric boundary conditions (open circuit) and Maxwell's electricity equation. The Rayleigh-Ritz approach is used to obtain natural frequencies and vibration mode shapes of the plate. Forced vibration response is obtained by using by the modal expansion method. In this paper, the Linear Quadratic Regulator (LQR), Linear Quadratic Gaussian (LQG) and FUZZY Logic Controller (FLC) are used to control and reduce the amplitude of the transverse deformation of a laminated composite rectangular plate which is excited by external force. In the numerical results, the effect of various inputs, e.g. positions of the external force, on the responses of the system are examined and discussed in detail. The proposed analytical method is validated with available data in the literature.
