SHAPE CONTROL OF SMART COMPOSITE STRUCTURES USING SMA AND PZT ACTUATORS

  • 摘要: 基于有限元素法求解嵌入SMA和PZT作为联合变形驱动器的板壳型智能结构的变形,采用优化方法将最小化目标变形和实际变形差作为目标函数,确定各个驱动器的驱动电压或控制温度以实现自适应结构的任意变形控制,并考虑到了控制电压和结构温度的限制。算例结果列举了联合控制同单独PZT或SMA控制方式的控制效果对比。
    Abstract: 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.
