Electromagnetic bearing control method, device and system

The invention provides an electromagnetic bearing control method, device and system. The method comprises the steps of obtaining operation data, collected by a bearing controller, of a target electromagnetic bearing; inputting the operation data into a preset fault prediction model for fault prediction to obtain a fault prediction result; when the fault prediction result is that a fault exists, analyzing the operation data to determine a fault type; and performing operation control on the bearing controller according to the fault type. Therefore, possible faults are predicted by collecting the operation data of the electromagnetic bearing through the bearing controller, when it is predicted that the bearing faults will occur, the fault type is determined according to the operation data, then operation control is conducted on the bearing controller, and the bearing operation fault rate and the rotor damage rate are reduced by conducting control intervention in advance; the bearing control performance is improved, the control effect is improved, and the stability of the whole system is improved.
