ABSTRACT

In the practical application of artificial light source type plant factories, the temperature and humidity environment is a dynamic environment with strong coupling and strong time delay. In the face of complex and changeable situations, the control strategy after the decoupling of the temperature and humidity dynamic environment model system needs to be control loop for effective control. This paper will use the relevant theory of internal model control to study the temperature and humidity control system, design an environmental controller to solve the coupling problem and time delay problem of the temperature and humidity environment, and simulate the process of the internal model control under the closed-loop control state. The timely tracking ability of the output signal of the inspection system under the changing working conditions will lay a theoretical foundation for the implementation and verification of the next temperature and humidity on-site control.
