Many nonlinear factors of a rotor system are amplified because of the off-center of the rotor. In this paper, a new control method of the rotor system is put forward, and it is to combine electromagnetic bearing control with a extruded oil-film damper. It controls actively the centrifugal force produced by the nonbalance of the rotor system, so the impack and friction between rotor and stator. The dynamic model and control block diagram of the system are presented. Its simulation calculation is conducted, and the result shows that the active control method is feasible.
