基于x-RLMS算法的自适应有源隔振技术研究

Investigation in Active Vibration Isolation Based on x-RLMS Algorithm

基于数字信号处理领域的 RL MS算法 ,构造了一种适用于柴油机双层隔振装置有源控制的自适应 x- RL MS算法。该算法可消除振动有源控制系统中存在的次级振源振动耦合通道和误差通道的影响。针对一个双层隔振模拟试验台架进行有源隔振仿真和试验 ,取得了较满意的控制效果。

Based on RLMS algorithm in digital signal processing,an adaptive x-RLMS algorithm,which is applied for a diesel two-stage vibration isolating system,is derived in this paper.It is verified that the affects introduced by the coupling channel and error channel would be improved.Computer simulation and experimental investigation are made,the results are satisfactory.
