Greenhouse Temperature Control System Based on Fuzzy Theory

The purpose of this paper is to present an adaptive method based on fuzzy control for temperature control in the greenhouse. First of all, a mathematic model was constructed for the air temperature in the greenhouse. Then the corresponding fuzzy control system was implemented by using the Simulink tools of MATLAB. At last, fuzzy controller was realized using Visual Basic (VB) in the upper machine in order to verify the system correct or not. The results show the validity and reasonability of the fuzzy control strategy for the temperature control in the greenhouse.
