The invention discloses a control method for realizing resuspension of a magnetic bearings system after temporary loss of control, and belongs to the field of magnetic bearings system. The control method for realizing the resuspension of the magnetic bearings system after the temporary loss of control is characterized in that a rotor position control module in a controller is used for controlling when the magnetic bearings system works normally, and a combined electromagnetic attracting force in direction opposite to the direction that the rotor deviates from a balance position can be applied to a rotor, thus ensuring that the rotor can be kept in the balance position where the suspension is to be stabilized; in case that the magnetic bearings system is subjected to temporary loss of control, a rotor speed control module in the controller is switched to control in order to apply the combined electromagnetic attracting force in the direction opposite to the rotor vibrating speed direction to the rotor, thus dissipating the rotor vibration energy caused by external distributing force, and as a result, the rotor vibrating speed can be reduced; then the rotor position control module in the controller is switched to control to enable the rotor to return to the balance position where the suspension is to be stabilized, so as to realize resuspension; the operation is convenient.
