This paper deals another viewpoint of the variable structure control for the nonlinear systems. The implementation of the variable structure controller on a hydrographic system consisting four tanks shows the effectiveness of the method chosen for systems having a high nonlinearity. To reduce the reluctance effect on the control member is acted upon the switching gain, which depends on the upper limits of the uncertainties of the system. A comparison of variable structure controller with that proportional integral regulator is done to highlight importance of this control technique.
Author Keywords: Sliding mode control, robustness, educational tool, level regulation, nonlinear, gain switching.

Abstract
This paper deals another viewpoint of the variable structure control for the nonlinear systems. The implementation of the variable structure controller on a hydrographic system consisting four tanks shows the effectiveness of the method chosen for systems having a high nonlinearity. To reduce the reluctance effect on the control member is acted upon the switching gain, which depends on the upper limits of the uncertainties of the system. A comparison of variable structure controller with that proportional integral regulator is done to highlight importance of this control technique.

Abstract: (french)
Ce papier traite un autre point de vue de la commande à structure variable des systèmes non linéaires. L'implantation du régulateur à structure variable sur un système hydrographique constitué de quatre réservoirs montre l'efficacité de la méthode choisie même pour les systèmes ayant une forte non linéarité. Afin de diminuer l'effet de réticence sur l'organe de commande on agit sur le gain de commutation, qui dépend des limites supérieures des incertitudes du système. Une comparaison du régulateur à structure variable avec celui du régulateur Proportionnel Intégral est effectuée pour mettre en évidence l'importance de cette technique de commande.
Author Keywords: Commande par mode de glissement, robustesse, outil pédagogique, régulation de niveau, non linéaire, gain de commutation.
