基于镜像修正FxLMS控制算法的船舶管路振动主动控制
Active control of ship pipeline vibration based on mirror-modified FxLMS control algorithm
摘要
Abstract
In response to the demand of ship pipelines for vibration damping and shock resistance,an active control strategy for pipeline vibration was designed based on the mirror-modified FxLMS algorithm.Such a strategy can ef-fectively control the vibration of a pipeline at low frequencies,and following a sudden change in the secondary pas-sage,the control system can rapidly converge again for stable control.First,theoretical research was conducted on the MMFxLMS algorithm to analyze the iteration and control of the algorithm,verifying the convergence and stability of the algorithm under different reference signal inputs through simulation.Finally,an experimental bench was con-structed to verify the actual control effect of the algorithm through experiments.The experimental results showed that the control strategy can reduce the vibration intensity by 15.37%in the active control of pipeline vibration,8.85%higher than the control effect of the FxLMS control strategy.Therefore,the MMFxLMS algorithm can effec-tively control pipeline vibration over time.关键词
