摘要：
A smart structure embedded with SMA and PZT as united actuators is solved by finite element method. Piezoelectric patch and shape memory alloy slim are bonded to its surface or embedded within the laminate. The applied voltage of PZT and the temperature of SMA are given for any plate shapes using optimization algorithms, with the difference between the desired and actual shapes as the objective function, and the constraint of the applied voltage and temperature is considered. The comparison among the effects of different control methods is given.
