The Application of Fuzzy Control in Greenhouse Environment Control

Abstract:

For the control of greenhouse environment parameters, a combined control system of the temperature and humidity inside the greenhouse according to the fuzzy control theory is design, which is of distributed control structure. The whole control system is divided into upper computer (personal computer) and the lower machine (SCM). Upper machine and lower machine adopt the Modbus fieldbus to communicate, which can effectively improve the efficiency of communication, to ensure accurate communication. Tracking control of temperature and humidity in the control system uses fuzzy control technology, which can effectively summarize and utilize human control experience, and regulate the environmental parameters according to need of crop growth automatically. Finally, through experiment, it is proved that the control system has achieved the anticipated target.
