摘要
加氯消毒过程具有大延时、大滞后、时变等特性,且干扰多,要实现对其良好的控制比较困难。采用模糊控制算法改进常规PID控制器,使PID参数的整定不依赖于对象数学模型,并且参数能够在线调整,满足实时控制的要求,实现了较好的余氯控制效果。
For chlorine disinfection process with large delay and time-varying characteristics,it is difficult to achieve a good control.In this paper,a fuzzy control algorithm is used to improve the conventional PID controller,which making PID parameter setting being not dependent on the object model,and the parameters can be adjusted online,the requirements of real-time control are meet,and a good control effect of residual chlorine is achieved.
