Abstract

Based on the block normalized least mean square algorithm, the control law is designed for the self-developed electromagnetic suspension vibration isolator. The algorithm does not need to model the secondary channel, and the structure is simple and easy to implement. Apply the algorithm to the electromagnetic suspension vibration isolation system, which has non-linear characteristics, and design active vibration control experiment on the electromagnetic suspension vibration isolation system. The experimental results show that the control algorithm can achieve fast convergence rate and obtain a good vibration isolation effect.

Key words
