Abstract
This paper presents a new modeling method and control system design procedure for a flexible rotor using active magnetic bearings as actuators for vibration control also. The goal is to let the flexible rotor revolve above the second whirling speed. To express the motion and the vibration by using a unified model, the new modeling method named specified for Extended Reduced Order Physical Model is applied. A LQ controller to suppress the vibration of the rotor and a PID controller to levitate the rotor are designed by using the unified model. Control simulation and experimental results are shown.
