摘要

针对自行研制的磁悬浮隔振器进行自适应前馈控制，设计了基于滤波x最小均方(Filtered x Least Mean Square----滤波x-LMS)算法的控制律。为了将滤波x-LMS算法应用于带有非线性特性的磁悬浮隔振系统，对滤波x-LMS算法进行了改进。在磁悬浮隔振系统上进行振动主动控制实验，实验结果表明，该控制算法取得了良好的减振效果。

Abstract

Adaptive feed-forward control was developed for the electromagnetic suspension vibration isolator, which was designed independently. Filtered x Least Mean Square (Filtered x -LMS) algorithm was designed. In order to apply filtered x -LMS algorithm to the electromagnetic suspension vibration isolation system, which has non-linear characteristics, Filtered x -LMS algorithm was improved. Active vibration control experiment was designed on the electromagnetic suspension vibration isolation system. The experimental results showed that the control algorithm obtained a good vibration control effect.
