This paper proposes new modeling technique and control system for multiple modes vibration control of a flexible rotor supported by active magnetic bearings. The purpose of our study is to rotate a flexible rotor with high rotation speed that exceeds critical speed of the second elasticity mode. To achieve this, vibration as well as motion has to be controlled. According to this purpose, new modeling technique named as "extended reduced order physical model" that can express both motion and vibration simultaneously is presented. Using this model, a PID controller to levitate the rotor and a LQ controller to suppress vibration of the rotor are designed. The performances of these controllers are examined through computer simulation.
