PLC实现的模糊PID控制器研究

The Research of Fuzzy PID Controller Based on PLC

设计了模糊PID控制器,在MTLAB环境下离线计算出了查询表,采用西门子S7-300在Step7软件中利用查表法实现了程序的设计。结合一阶模型进行实验,结果表明,这种方法能在线调整PID参数,取得了不错的效果。

The paper designed the Fuzzy PID controller and calculated the inquiring table offline with MATLAB. By SIEMENS S7 - 300, the program is completed by using the method of inquiring table in Step7 soft - ware. With the proof of the first order model,it indicates that this method can adjust the PID parameter on line .
