Design of a new measurement and control system of CO2 for greenhouse based on fuzzy control

A greenhouse carbon dioxide concentration measurement and control system is designed based on fuzzy control with infrared carbon dioxide gas sensor, and the choice of the control structure parameters are given. According to the experience, the main points of the design of control rules are induced, and the carbon dioxide concentration fuzzy controller is constructed with relevant fuzzy logic. The modular structure is used for system hardware and software design, enhance the versatility and flexibility of the use of system. The application shows that the carbon dioxide measurement and control system achieved using fuzzy control is running stable, fast response, has broad application prospects.
