摘要
针对火电厂水质调节系统控制对象的大时滞时变性,模型不确定等特性,设计了了模糊免疫PID-Smith预估控制系统。仿真结果表明,所设计的控制系统比常规PID控制系统具有较强鲁棒性,系统具有良好的适应能力,适用于缺乏精确数学模型且参数变化的大纯滞后工业过程。
Aiming at the large time delay and mutable and uncertainty characteristic of the controlled object for the water quality adjusting system in power plant,a control system based on Fuzzy immune PID-Smith controller is proposed in this paper. The simulation and application show that the robustness of this control system is superiors to general PID predicting control system.Owingto the good fitness of this control method,it can be used in large delay industry process of uncertain model and variationalparameters.
