- Abstract
Aiming at the current driving and support problems of fuel cell air compressors, an air-magnetic suspension type air compressor was proposed integrating foil dynamic pressure bearing and power magnetic bearing. Based on the structural composition of the air compressor, the mathematical models of the air compressor magnetic suspension support force, air suspension support force, and rotor dynamics air compressors were established. Based on the state space equation of the dynamic model of the fuel cell air compressor rotor system, a strong anti-interference collaborative controller was designed, and key physical parameters such as speed, driving torque, rotor suspension displacement, and electromagnetic regulating force were compared and simulated. The results show that collaborative control in response, anti-interference, and robustness are outperformed than PID control. A control experimental platform was established based on collaborative control and PID control, and the analysis was conducted on the air-magnetic suspension of the air compressor rotor, further the excellent control effect and control performance of collaborative control were verified.
