| Abstract: | The structure of fuzzy PID control and the fuzzy PID controller designing are analyzed in this article,so does the PLC implementation of fuzzy PID.Taking type PCT-II process control system experimental device as a Mock Object,the Liquid level's fuzzy PID control is realized based on S7-300PLC.Results shows that the fuzzy controllers consist of PLC are both simple and practical,and the performance of system is improved. |
