【Abstract】 A magnetic levitation support rotor system is established to replace mechanical bearings, aiming to avoid the problem of bearing locking due to thermal expansion. The rotor suspension control system model of the vacuum pump drive motor is built in MATLAB/Simulink, and a PID parameter optimization algorithm for active magnetic suspension is given. Relying on the improved fuzzy PID controller for dynamic simulation, the simulation results show that the PID optimization control has a positive effect on the magnetic bearing control.更多还原
