自适应主动振动控制仿真分析
Simulation Analysis of Adaptive Active Vibration Control
摘要
Abstract
In FxLMS adaptive algorithm, secondary path can affect the diagonality of the filtered self-correlation matrix and the divergence of the eigenvalues, causing a slower convergence for the algorithm. In this paper, an improved FxLMS algorithm——SOFxLMS algorithm is proposed to reduce the influence of the secondary path and increase the convergence speed in active vibration control. The active vibration control simulation models based on the plain FxLMS algorithm and SOFxLMS algorithm are set up respectively in Simulink. On the promise of ensuring the stability of the system, the two kinds of algorithms are compared by simulation analysis under the same circumstances. The results show that the SOFxLMS algorithm has better control effect than that of FxLMS algorithm under the conditions of lower order filter and larger iteration step size.关键词
