In　this　paper,　the　dynamic　behavior　of　piezoelectric　laminates　is　investigated.　Thin　piezoelectric　layers　are　assumed　to　be　embedded　on　the　top　and　the　bottom　surfaces　of　the　rectangular　plate.　The　top　and　the　bottom　layers　are　taken　as　the　actuator　and　sensor,　respectively.　Based　on　Von　Karman　theory,　the　geometrically　nonlinear　relation　between　strain　and　displacement　is　proposed　and　basic　large　deformation　equations　are　established.　Nonlinear　dynamic　equations　of　piezoelectric　laminates　are　formulated　using　Hamilton＇s　principle.　The　Galerkin＇s　approach　is　applied　to　partial　differential　equations　to　obtain　the　ordinary　differential　equations.　The　numerical　results　show　the　existence　of　periodic,　bifurcation　and　chaotic　motions　for　the　laminated　piezoelectric　rectangular　plate　with　the　changes　of　frequency　and　amplitude　of　forcing　loads.　Furthermore　we　can　control　the　vibration　of　the　piezoelectric　laminates　using　a　constant　gain　velocity　minus　control　algorithm.　Using　the　control　gain,　the　free　vibration　of　the　plate　is　damped　out　more　quickly,　and　the　nonlinear　dynamic　behavior　varies　from　the　system　without　control.　Finally,　a　numerical　simulation　example　shows　that　the　method　suggested　in　this　paper　is　effective　and　simply.
