积分分离模糊PID控制在中央空调温湿度控制中的应用

The Application of Integral Apart Fuzzy PID Control in the Central Air-conditioning's Temperature and Humidity Control

提出在中央空调温湿度控制系统中,基于常规模糊PID控制器,引入积分分离PID控制思想.当系统调节开始时由于系统误差较大,系统的积分系数为零,系统的控制主要由模糊PD控制来实现;当系统误差较小时加入积分控制环节,系统切换为模糊PID控制,从而改善和提高系统的控制性能.

This paper proposes to introduce the theory of integral apart PID control in the central air-conditioning＇s temperature and humidity control based on the routine fuzzy PID controller. While the integral modulus is zero because the system error is big at the beginning of system adjustment, the control mostly depends on the Fuzzy PD control. When the error is smaller, the integral control taehe is added, the system switches to Fuzzy PID control so as to improve the capability of the system.
