Aiming at the control of eight-pole heteropolar radial hybrid magnetic bearing (HRHMB), The Magnet-Simulink
co-simulation method is proposed. First, the program block diagram of PID control magnetic system is built in Simulink. Then
the model of the eight-pole HRHMB in Magnet is imported into the control program of Simulink. Finally, the Magnet-Simulink
co-simulation model of the eight-pole HRHMB system controlled by PID is established
