一种应用Fx LMS算法的双层隔振试验装置
Double-layer Vibration Isolation Experimental Equipment Based on Fx LMS Algorithm
摘要
Abstract
In active vibration control, the existence of the secondary paths may reduce the control effect. In this paper, the Filter-x Least Mean Square (Fx LMS) adaptive filtering algorithm is used to reduce the influence of the secondary paths. The adaptive control is realized by adjusting the step size for filter parameters updating. The compact-RIO (c RIO) controller is used in the platform and the Lab VIEW code is used for programing. The active control of different systems is realized by setting different parameters. This control process can be divided into three steps: setting parameters, identification of secondary paths, and control of the error signals. Based on the theory and simulation of the adaptive algorithm, the c RIO platform is used to realize the experimental research of the real-time active vibration control. The active control is realized by using the adaptive algorithm based on the double-layer vibration isolation system. And an ideal control effect is achieved.关键词
