摘　　要：为解决常规PID调节器很难满足在线回转误差检测与控制要求的问题,以静压气体轴承回转误差控制系统为研究对象进行了探讨,提出了模糊自整定PID控制策略。根据模糊控制理论,运用常规PID控制器的设计方法,设计出了模糊自整定PID控制器,实现了PID控制器参数在线自调整。仿真试验表明,与传统的PID控制相比,模糊PID控制系统具有良好的稳定性和自适应能力。Since the conventional PID controller is difficult to meet the requirements of on-line error detection and control, with rotary error control system of hydrostatic gas-lubricated bearing as the study object, this paper proposed serf-tuning fuzzy PID control strategy. According to the fuzzy control theory and using design method of conventional PID controller, it designed serf-tuning fuzzy PID controller, and realized on- line serf-tuning of PID controller parameters. The simulation test indicates that the fuzzy PID controlling system has excellent stability and serf- adaptation compared with conventional PID controller.
