Union d'une commande par backstepping avec une commande locale (1503.03900v1)

Abstract: Systems for which the backstepping technique cannot be applied are considered. A criterion for the design of a hybrid feedback law is proposed by blending a local stabilizer with a backstepping controller. This hybrid feedback law renders the origin globally asymptotically stable for the closed-loop system. The selection criterion is based on choice of the size of a compact set included in the basin of attraction of the local controller. The results are illustrated by simulations.
