针对中央空调水系统非线性、大滞后、难以建立精确的数学模型等特性，本文对其常用的PID控制作了改进，将依赖于专家控制经验而不依赖系统精确模型的模糊控制与PID控制相结合，设计了自整定模糊PID控制器。通过对中央空调冷冻水系统的仿真研究，结果表明改进后的PID控制在超调量、调节时间、抗干扰能力等性能指标上较之PID控制都有明显优势。

The central air-conditioning water system is nonlinear, large delay, and it is difficult to establish accurate mathematical model. This paper improves the conventional PID, combine PID control and fuzzy control which depend on expert control experience and does not depend on the precise system model, design the self-adaptive fuzzy PID controller. Through the simulation research of the chilled water system, the results show that the improved PID control in overshoot, settling time, anti-interference performance than the PID control has a distinct advantage.
