This paper is on the subject of active vibration control of flexible rotors supported by magnetic bearings. Using a finite element method for the mathematical model of flexible rotors, we have formulated the eigenvalue problem taking into account the interaction between a mechanical system of a flexible rotor and an electrical system of magnetic bearings and a controller. However, gyroscopic effects are disregarded in this paper for simplicity. We will be able to adapt this formulation to a general flexible rotor-magnetic bearing system. Controllability with and without collocation is discussed for the higher-order flexible modes of the test rig. In conclusion, we have proposed that it is necessary to add new active control loops for the higher-order flexible modes even in the case of collocation. Then, it is possible to stabilize for the case of uncollocation by means of this method.
