摘要

针对自行研制的磁悬浮隔振器，设计了基于分块归一化LMS（Block Normalized Least Mean Square）算法的控制律。该算法不需要对次级通道进行建模，且结构简单，易于实现。把该算法应用于带有非线性特性的磁悬浮隔振实验平台，并对其进行振动主动控制实验。实验结果表明：该控制算法收敛速度较快，取得了良好的隔振效果。

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.
