基于分数阶FxLMS的浮筏-圆柱壳主动控制方法
Research on Active Control Method of Floating Raft and Cylindrical Shell Systems Based on Fractional-Order FxLMS
摘要
Abstract
To suppress low-frequency line-spectrum vibrations in mechanical equipment such as the main and auxiliary machinery of undersea vehicles,this paper proposed a dual-channel fractional-order filtered-x least mean square(FxLMS)algorithm based on the fractional-order gradient descent method.The control performance of algorithms with different fractional orders was analyzed and compared through simulations.An experimental platform for active vibration control based on a floating raft and cylindrical shell structure was established.Comparative experiments under various operating conditions demonstrate that compared with single-channel control strategies,the proposed dual-channel collaborative control scheme exhibits significant advantages in suppressing the overall vibration of the floating raft and cylindrical shell system.It can effectively avoid the phenomenon of local vibration amplification.Under dual-frequency line spectrum excitation,this method still demonstrates good control effectiveness and engineering practicability.This study can provide reference and technical support for the active control of low-frequency vibration in ships and undersea vehicles.关键词
