Abstract :
This paper deals with the control under sampling of nonlinear singularly perturbed systems. Discretization schemes for such systems are proposed, on the basis of a two time scale control law. The control under sampling of synchronous motors in a (α-β) representation is considered as a case study. This allows us to underline some pathology due to the discretization and reduction of this kind of nonlinear systems
