Summary: | Currently in Tunisia, agricultural greenhouses paramount importance since it contributes to creating a microclimate in terms of humidity, temperature, vegetation cover and air support within the needs of the plant tomato. Such greenhouses are usually designed in ways to control mainly the temperature and relative humidity inside. As an expert and researcher farm, we found that the disease of "blight" in crop plants in greenhouses and due to a bad compromise between temperature, relative humidity and ventilation of the greenhouse. The three parameters mentioned above are disrupted by external weather conditions but can also be affected by irrigation, evapotranspiration, etc. To establish this compromise, knowing that the greenhouse system is nonlinear, we must be aided by the identification of the system that is to say the determination of its mathematical model based on experimental observations input-output. For the output of the model is the closest to the real system within a fixed criterion, we must estimate the values of model parameters based on the input-output observations (I/ O). This work is done in order to design, predict, control and simulate the greenhouse system. |
