In this paper, a rectangular plate made of functionally graded materials (FGMs) with piezoelectric sensor and actuator is considered. Based on the classical plate theory assumptions, by using strain-displacement relations and Maxwellʹs equation, the equation of motion is obtained and by using Navier solution the equation of motion is solved. Then the frequency of laminate plate with edge simply supported condition is obtained. The present analysis is validated by comparing results with isotropic rectangular plate without piezoelectric layers. Finally, different plots were obtained and the effect of sensor and actuator on vibration amplitude is discussed.
