摘要
基于西门子公司S7- 2 0 0系列PLC ,扩展模拟量处理模块 ,应用PID算法 ,实现对模拟量的闭环控制 ,提出了PID控制算法的实现方法和步骤 ,给出了水箱液位控制应用实例。
Base on SIEMENS S7-200 series PLC, the extended simulation quantity processing module, and the applied arithmetic of PID, the achieved closed loop control of simulation quantity were introduced. The achieving method and step of PID control arithmetic, and an example for water level control of water tank were given.
