模糊增益調(diào)整PID 控制在VAV 系統(tǒng)中的應(yīng)用

本文針對用普通PID控制對VAV系統(tǒng)控制參數(shù)難以整定的問題,設(shè)計了一種基于模糊控
制原理的PID參數(shù)在線自調(diào)整控制器,根據(jù)偏差和偏差變化率來實時調(diào)整p K ， i K ， d K 參數(shù)。通過計算機(jī)仿真結(jié)果表明，這種模糊增益調(diào)整PID控制器比常規(guī)PID控制器有更好的控制效果，大大改善了系統(tǒng)的動態(tài)和穩(wěn)態(tài)性能。

Abstract: Due to the current PID control is difficult in parameter tuning in VAV air conditioning system, a method of fuzzy PID gain setting control is designed in this paper , which can set the parameter p K ， i K ， d K ontime. Computer simulation results show that the fuzzy PID gain setting control method is superior to current PID control, and greatly improves the dynamic capability and stabilization capability.
