基于组态王和PLC的模糊PID水压控制研究

本文介绍了S7-300的基本功能和模糊控制的基本原理，详细阐述了如何利用step7编写用户自行开发的模糊PID控制算法和如何利用组态王6.5对供水管网水压进行监控。通过组态王和S7-300之间的通信，采用模糊PID控制算法实时调节P、I、D参数，实现了对供水管网水压的控制。

Research of Fuzzy PID Control for Hydraulic Pressure Based on Kingview and PLC WEI Rui-Lu LUO Qi-Ping (Department of Electrical Engineering,Guangxi Technological College of Machinery and Electricity,Nanning,530007) Abstract: The basic functions of S7-300 and the basic principle of fuzzy control are introduced，how to use the step 7 to programme the user-developed fuzzy control algorithm and how to use Kingview 6.5 to monitor the hydraulic pressure of water supply piping are described. Through the communication between Kingview 6.5 and S7-300，by adjusting the P,I,D parameters real-time using the fuzzy PID control algorithm , the control of hydraulic pressure is realized.
