In order to control the vibration of a rotating shaft, we propose a rotor-shaft system supported by flexible bearing pedestals which are installed in electromagnetic actuators. These actuators are controlled by the PID-type algorithms and can apply an electromagnetic force to the bearing housings. When a rotor is mounted at the midpoint of a shaft, the rotor-shaft system can be modeled by a two-degrees-of-freedom system. The principle of a dynamic absorber is applied to this system and the optimal dynamic parameters of the pedestals are calculated. In the experiment, the stiffness and damping coefficients of the pedestals are regulated to the optimal values by setting the gain of the controllers up, and very effective vibration control of the rotor-shaft system may be confirmed by using this apparatus.
