摘　　要：以过程控制实验装置的水箱液位系统为被控对象,PLC作为控制器,电动阀为执行器,在建立液位系统的数学模型的基础上,采用PID控制算法,对其参数进行了整定,构建了系统的MCGS组态环境,并在该环境下进行了调试。调试结果表明,系统运行稳定,超调量为18%,调节时间约为3min,控制指标达到了工程要求,控制效果良好。The process control experimental system takes the water level as the controlled ohject. In this system PLC is adopted as a controller and the electric valve for the actuator. Based on the water level system in the establishment of the mathematical model, the system uses PID algorithm, the PID parameters are tuning, MCGS configuration environment is buih and debugs in the environment. Experiments show that the system is running smoothly, the overshoot is 18% , the setting time is about 3 rain. The control indicators have reached the engineering requirements and the control effect is good.
