磁悬浮隔振器的自寻优前馈控制

Self-optimizing feed-forward control of electromagnetic suspension vibration isolator

以船舶的振动主动控制为背景,基于自行研制的磁悬浮隔振器,提出了前馈控制的主动隔振方案,设计了对控制器参数在线自寻优的算法。该算法能够用于具有非线性特性的磁悬浮隔振器,并且不需要建立主动力到控制目标点的通道模型。在磁悬浮隔振系统上的实验结果表明,该控制算法取得了良好的减振效果,并且当系统受到扰动后,能够实现寻优过程的自动启动。

In the background of active vibration control of ship,an active vibration isolation program of feedforward control was proposed,and an online self-optimizing algorithm for the controller parameters was designed based on the electromagnetic suspension vibration isolator, which was designed independently. The algorithm can be used for the electromagnetic suspension vibration isolator with non-linear characteristics, and does not require the channel model of active force to the target point.The experimental results on the electromagnetic suspension vibration isolation system show that the control algorithm obtains a good vibration control effect, and the optimization process can restart automatically with system disturbances.
