摘　　要：针对传统的温室空调冷冻水控制系统效率较低、误差和能耗较大的问题,提出了基于免疫PID控制系统的控制理论,研究了免疫PID控制算法及其控制器的设计过程,利用该算法对冷冻水系统进行了控制,对冷冻水系统控制器进行设计和优化,形成了温室空调冷冻水闭环控制系统。针对已有的冷冻水系统,使用免疫反馈PID控制器、普通PID控制器以及模糊PID控制器分别进行了控制模拟,比较了输入功耗曲线、温度曲线和输出水温误差曲线,指出免疫PID控制器在冷冻水出水温度以及功耗上优于传统PID控制器和模糊PID控制器,达到了提高控制精度、降低能耗的目的。In order to solve chilled water temperature regulation problem of traditional greenhouse air conditioning,this paper presents the chilled water intelligent control theory based on immune PID control system.It studies the immune PID control method and the design process of immune controller,uses the algorithm to control the chilled water system and optimize the controller,then the closed-loop chilled water control system of greenhouse air conditioning is formed.The PID controller with immune feedback,traditional PID controller and fuzzy PID controller are used for simulation experiment,and their input pow-er curve,temperature curve and output water temperature error curve are compared.Results show that the immune PID controlleris better than traditional PID controller and fuzzy PID controller,and it achieves the purpose of high control precision and low energy consumption.
