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

In the background of active vibration control of ship,an active vibration isolation program of feed-forward control was proposed,and an online self-optimizing algorithm for the controller parameters was de-signed 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 vibra-tion control effect,and the optimization process can restart automatically with system disturbances.
