Dynamic model of an agricultural greenhouse using Matlab-Simulink environment

Abstract

This paper presents a dynamic model of an agricultural greenhouse in order to predict the air temperature and the relative humidity using Matlab/Simulink environment. It describes the transfer of heat and water vapor inside the greenhouse during four days in winter. The simulation results showed that the temperature and the humidity of the internal air vary with the weather conditions (solar radiation, wind speed, outside temperature...), season, location and the structure of the greenhouse.
