摘　　要：空压机供气系统在水电站辅机控制系统中主要用来对水轮机制动和作为各系统、设备检修的动力,系统滞后性大、稳定性差。该文以PLC为硬件平台,采用模糊自整定控制策略,设计了PID参数模糊自整定的空压机恒压控制系统,对螺杆式空压机控制系统进行改造。仿真与运行结果表明:系统抗干扰能力强,输出压力误差(<2%)满足工艺要求,调节时间短,精度高,稳定可靠。Compressor in hydropower station auxiliary engine control system for the main purpose of turbine brake and as each system,equipment overhaul power,this system have big hysteresis and poor stability.Based on PLC for hardware platform,using fuzzy self-tuning control strategy,design the compressor constant pressure control system of fuzzy self-tuning PID parameters reform screw compressor control system.The simulation and operation results show that the system strong anti-interference ability,output pressure error（ 2%） meet the technological requirements,short setting time,high precision,stable and reliable.
