Hybrid control of a station of irrigation by sprinkling: Fuzzy supervisor approach

The spray under pressure is an effective save on water. This task should be automated and controlled in order to limit the water waste and the facilities of damages. For this reason, we find a mathematical model describing the irrigation process with the Takagi-Sugeno fuzzy model approach and the clustering technique. This paper presents the synthesis of a hybrid control applied to the station of irrigation by sprinkling, Based on the combination of the fuzzy logic approach and the PI controller, this method has the advantage of combining the performance of both controllers. A fuzzy supervisor manages the switching from one to another and regulates the rate of participation of each order. After presentation of mathematical model of our station, simulation results illustrate the performance of the control strategy.
