| 摘 要： | 本文介绍了一种水池恒液位的模糊PID控制系统的设计,该系统利用西门子S7-200PLC实现对液位的模糊PID控制,通过建立模糊控制规则和进行模糊推理对PID的三个参数进行在线整定,液位的值作为反馈信号由液位传感器将传给PLC.实验仿真和实际测试表明,采用模糊PID控制的蓄水池液位,较常规PID控制响应速度快,超调量较小...

| Abstract: | A fuzzy-PID control system for constant liquid level is designed in this paper,in which S7-200PLC from Siemens is adopted to control the liquid level.The parameters of PID-controller such as Kp、Ki、Kd are set online by building the fuzzy tuning rules and completing fuzzy reasoning.PLC receives the signals from liquid level sensors as feedback.The simulation and tests show the fuzzy-PID controller can make the liquid level control system have better control performances than single PID control system,such as faster response time,smaller overshoot and shorter time to reach steady state and improved system performances can be achieved. |
