To achieve the rotor’s high precision suspension control of bearingless induction motor, a kind of convenient vibration compensation and control method is presented. The inverse model of magnetic suspension system is established, and by inverse system method, the decoupling control between two radial displacement components are achieved firstly; after then, through the compensation of unbalanced vibration control current, the compensation control force of unbalanced vibration that is used to counteract the unbalanced exciting force of bearingless rotor, is generated. Simulation results have shown that when adopting the proposed control strategy, the unbalanced vibration of bearingless rotor can be inhibited effectively either in the start stage or in the steady operation state.
