【摘要】 研究了基于FxLMS算法的多通道解耦控制方法,以解决多通道振动主动控制中多作动器抑制系统全局振动的技术难题,改善各个通道耦合串扰的缺点,减小串扰对系统稳定性的影响。提出了将通道串扰影响考虑在内的修正解耦算法,并理论上推导该算法,对比了修正算法与经典算法的振动控制效果,试验与仿真结果的一致性表明:修正算法具有更好的控制效果和控制稳定性,在单频和多频振动控制方面都具有优越性。更多还原

【Abstract】 To solve the technical problem of multi-actuator suppression global vibration in multi-channel vibration active control,improve the shortcomings of coupling crosstalk in each channel,and reduce the influence of crosstalk on system stability,the multi-channel decoupling control method based on FXLMS algorithm is studied.A modified decoupling algorithm considering the influence of channel crosstalk is proposed,and the algorithm is deduced theoretically.The vibration control effect of the modified algorithm and the classical algorithm is compared.The consistency between the experimental and simulation results shows that the modified algorithm has better control.The effect and control stability are superior in both single-frequency and multi-frequency vibration control.更多还原
