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.
