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.
