Abstract

This paper presents an experimental study on the vibration control of a viscous liquid-filled rotor using two active magnetic bearings. The magnetic bearings are placed at both ends of a rigid shaft connected to the rotor. In order to support the rotor system and to suppress the unstable whirling motion, the gain-scheduled system based on conventional PD control law is proposed. In addition, a first-order delay filter is also introduced to improve noise sensitivity. The gain schedule system was formed in the experiment by scheduling control parameters of the PD controller with the related rotating speed at which the rotor system is stable. The validity of the control system has been verified by the experiment.
