A hybrid smart structure integrated with shape memory alloy slims and piezoelectric ceramic patches as united actuators, was presented and modeled by finite element methods. Being bonded to its surface or embedded in the laminate, the piezoelectric ceramic patches was treated as a certain layer while the shape memory alloy slims as the load subject to the temperature. The comparison among the effects of different control methods was given, and validated with static experiment. The result indicate that the shape control of the hybrid smart structure can take advantage of their characteristic with shape memory alloy actuators holding the mostly load and piezoelectric ceramic actuators correcting the precise shape.
