In the present paper, the effects of using piezoelectric sensor and actuator layers on the vibration of FGM plates are investigated. In this regard, free vibration, forced vibration and active control of the transient vibration are studied. In the free vibration analysis, natural frequencies and mode shapes are determined. In the forced vibration analysis, the responses of the system are obtained for different inputs and different electric potential fields. The finite element method is employed to solve the governing equations. It is noticed that the piezoelectric layer has minor effects on the natural frequencies and no effect on the mode shapes. Instead, sensor and actuator piezoelectric layers may be used in active control of the transient vibrations of the systems without performing any modifications on the vibration parameters.
