摘要
本文设计了一种基于可编程逻辑控制器(PLC)和变频器的具有远程监控功能的冷媒水自动控制系统。采用模糊PID算法对管网压力进行控制,弥补了传统PID控制的不足,改善了系统的非线性、大滞后性,提高了系统的鲁棒性。
A kind of refrigerant water automatic control system with remote supervision function based on PLC and frequency transformer is introduced.The Fuzzy-PID arithmetic is used to control pipe network for constant pressure.The method has made up the disadvantage of The traditional PID control and improved the nonlinearity,serious lag and robustness of the system.
