摘要
针对自行研制的磁悬浮隔振器进行自适应前馈控制,设计了基于滤波x最小均方(Filtered x Least Mean Square——滤波x-LMS)算法的控制律。为了将滤波x-LMS算法应用于带有非线性特性的磁悬浮隔振系统,对滤波x-LMS算法进行了改进。在磁悬浮隔振系统上进行振动主动控制实验,实验结果表明,该控制算法取得了良好的减振效果。
Adaptive feed-forward control was developed for an electromagnetic suspension vibration isolator designed independently.Filtered x-least mean square (filtered x-LMS) algorithm was designed.In order to apply the filtered x-LMS algorithm to the electromagnetic suspension vibration isolation system with non-linear characteristics,the filtered x-LMS algorithm was improved.Active vibration control experiment was designed for the electromagnetic suspension vibration isolation system.The experimental results showed that the control algorithm has a good vibration control effect.
