| 摘 要： | 给出了用两种材料对梁进行振动控制的综合控制方法。采用多层分布压电层进行精密主动控制时，将压电传感层和压电致动层分割成若干单元来设计压电模态传感器和压电模态致动器，进而实现了梁的模态控制，同时利用形状记忆合金的超弹性特性对梁进行被动控制来抑制梁的大振幅振动，取得了很好的控制效果。

| Abstract: | A hybrid control scheme for vibration control of smart beams is presented in which the passive control method is used to suppress the vibration with large amplitude by taking advantage of the supper elasticity of shape memory alloy, and the active control method is used simultaneously to perform precise control by using distributed segmented piezoelectric sensors and actuators. The simulation results show that control effect of the hybrid method is much better than that of the distributed piezoelectric element method itself. |
