| 摘 要： | 机敏结构是具有传感和执行双重功能的结构形式，无需外界帮助可自适应调节其状态。通过机敏结构建立了三维支撑结构的振动主动控制系统，利用Hamilton原理和变分法中的Euler公式导出了压电机敏结构的离散控制方程，采用加速度反馈实现了支架的振动主动控制。

| Abstract: | Smart structure has a good adaptability and a good functionality because of incorporating sensors and actuators. In this paper, the active vibration control system of a 3 Dimensional supporter is realized based on smart structures. The finite element control equations are derived from Hamilton principle and Euler equation. The experimental results are provided. |
