摘　　要：以20mm过程控制系统的管道流量系统为被控对象,以PLC作为控制器,变频器为执行对象,在建立流量系统的数学模型的基础上,采用PID算法,进行了参数整定,构建了系统的组态环境,并在该环境下进行了调试,系统运行平缓,控制指标达到了工程要求,调试效果良好。The system takes Ihe prneess control svslem with 20 mm pipe flow as the controlled object. PLC is adopted as a controller aud inverter for the actuator. Based on the flow system in the establishment of the mathematical model, it uses PID algorithm, the parameters are tuning, built system configuration environment and debugs in the environment. Experiments show that the syslem is running smoothly, the control indicators have reached the engineering requirements, and the debugging has a good effect.
