约束权函数的FxLMS算法的自适应有源隔振技术研究

Investigation in Active Vibration Isolation Based on a Weight-constrained FxLMS Algorithm

基于FxLMS算法,构造一种适用于双层隔振装置有源控制的自适应CFxLMS算法。该方法可降低参考信号干扰对误差通道的影响,提高系统的鲁棒性。针对某一基于磁致伸缩作动器双层隔振装置进行计算机仿真,结果证明该方法可有效改善系统性能。

Based on the FxLMS algorithm, a weight-constrained fihered-FxLMS（ CFxLMS） algorithm, which is applied for a two-stage vibration isolation system, is proposed for the broadband feedforward active vibration control system in this paper. Computer simulation of an active vibration isolation system based on giant magnetostrictive actuator shows that the robustness of the system gets improved.
