| Abstract: | Based on the balances of energy and mass, a modeling method taking the intelligent control of the greenhouse environment into account is proposed, the physical processes of energy and mass exchanges resulted from radiation, ventilation, convection and crop transpiration in greenhouse microclimate were analyzed, and the control models of temperature and humidity were studied according to the character of the greenhouse in China. By using the root mean squares error (RMSE) algorithm, the error between the simulated value and the measured one were simulated and analyzed. The results indicated that the dynamic model could provide reliable estimation of both temperature and humidity in a greenhouse. |
