【Abstract】 In order to improve the dynamic performance of magnetic-gas bearing,the fuzzy PID control algorithm was applied to magnetic-gas bearing with the characteristics of PID parameters adjusted in real time by fuzzy control. The simulation results show that the fuzzy PID control algorithm can effectively improve the adjusting time and overshoot of the system in benefit of magnetic-gas bearing with high control accuracy.更多还原
