抑制作动器间干扰的主动控制方法

通过优化作动器的控制目标,调整控制通道耦合方式,可有效抑制作动器间的正反馈,达到快速平稳收敛的控制目的。该方法基于滤波xLMS方法和多通道耦合控制模型,控制过程简洁、有效。实验结果表明,该方法能有效抑制多个作动器之间的互相干扰,而且较多通道分散控制具有更高的总体抑制性能。

Active Control Method for Suppressing Mutual Interference of Actuators

To solve the actuator mutual interference problem in the multi-channel active vibration control, control focus was adjusted and the coupling way of control channels was revised. By the revised way, positive feedbacks between the actuators have been suppressed effectively and control purpose has been achieved fast and stably. The revised way is based on the Filtered-x LMS(FxLMS) algorithm and the multi-channel control model. Control method is effective and stable. Realizing process is simple and practical. The experiment results show that this revised control method can effectively suppress interference between actuators, at the same time can meet higher overall control requirements.
