摘　　要：本文针对温室的环境特点和主要环境因子进行了分析,设计出了温湿度的传递方程及耦合方程,建立了温室温湿度的数学模型。在此基础上,利用对角矩阵对温湿度进行解耦分析,对温室系统进行传统PID控制。由于对角矩阵具有能将复杂的多输入、多输出系统转换为独立的一对一系统,本研究简化了控制器的设计难度,降低了系统的耦合性。This paper analyzes the environmental characteristics and main environmental factors of greenhouses,and designs the transfer equation and coupling equation of temperature and humidity,and establishes the mathematical mode of temperature and humidity of the greenhouse.On this basis,the diagonal matrix is used to decouple the temperature and humidity,to take the traditional PID control of the greenhouse system.Because the diagonal matrix has the ability to convert a complex multi-input and multi-output system into an independent one-to-one system,this research simplifies the design difficulty of the controller and reduce the coupling of the system.
