Development of a Fuzzy Logic Controller applied to an agricultural greenhouse experimentally validated

摘要

The agricultural greenhouse presents a complicated procedure since the strong perturbations and the important number of its input parameters, which have a great potential and capacity to influence the climate inside it. For this reason, a Fuzzy Logic Controller (FLC) is developed in order to promote a suitable microclimate by activating the appropriate actuators installed inside the greenhouse with the appropriate rate. The dynamic modeling of the studied greenhouse is presented and simulated under MATLAB/Simulink environment to be experimentally validated within the Research and Technology Center of Energy (CRTEn) in Tunisia. The simulation results illustrate the effectiveness of the proposed dynamic model to investigate the internal air temperature and relative humidity with a low percentage of error. In addition, the developed controller FLC presents an effective solution to get an optimized microclimate indoor the agricultural greenhouse.
