摘要:基于压电堆驱动器设计并制作了一台一维微振动主动隔振平台。利用振动加速度信号
和 FX-LMS 自适应算法,开发了一套自动控制系统。最后通过实验对其隔振效果进行了测
试和分析。结果表明,该一维微振动主动隔振平台具有良好的隔振效果,可广泛应用于各种
微振动主动隔离场合。

Abstract: Based on piezoelectric stack actuator, one dimension micro-vibration active isolation
platform has been designed and manufactured. Using vibration acceleration signal and FX-LMS
adaptive algorithm, a automation control system has been developed. At last, the isolation effect of the
one dimension active isolation platform has been tested and analyzed by experimental method. The
result includes that the one dimension active isolation platform has good isolation effect. It can be
applied to many kinds of micro-vibration active isolation occasions.

在实际工程环境中,结构振动多为低频及中低频振动,对其采用被动抑制方法很难达到
预期抑制效果,而主动控制技术对低频振动的控制则具有明显优势,其控制精度高,控制效
果好,且代价小。基于压电智
