2 Description of the Irrigation Station with Sprinkling

The French company LEROY SOMMER makes available to researchers an irri-

gation station (Fig. 1 ) with sprinkling but with practical constraints existing in the
real irrigation stations (Mejri et al. 2013 ), this station is composed of two parts:
hydraulic circuit and an electrical cabinet (Sommer 1996 ).

2.1 Practical Constraints of Irrigation Station

Before going to modeling our irrigation station, we will submit all practical con-
straints existing in the real irrigation stations, because the desired performances it is
necessary that it respects the following constraints:

Regulation of the fl ow and water pressure:

￿

Q ð F ; t Þ) Q ref

ð 1 Þ

P ð F ; t Þ) P ref

Constraints on the control:

￿

N min N ð t Þ N max ð 2 Þ

The fixed speed pump will be active or not. N the numbers of turns of the

variable speed pump.
