. Dans, Il concerne le fait d'assurer une transition stable entre deux points opérationnels d'un système non linéaire Cette approche emploie la stratégie de séquencement de gain et la notion d'incertitude bornée en norme pour approximer un système non linéairè a travers une famille de systèmes linéaires incertainsàincertainsà incertitude bornée en norme Autour d'un ensemble de points d'´ equilibre, des lois de commande locale sont déterminées en garantissant quelques spécifications de performances locales. Le séquencement est déterminé de sorte que la stabilité est garantie. Par interpolation polynômiale continue, une loi de commande continue estétablièestétabliè a partir des points d'´ equilibre trouvés hors ligne et des correcteurs associés. Une stratégie de commande séquencée par retour d'´ etat ainsi qu'une stratégie par retour de sortie dynamique ontétéontété envisagées. Dans le premier cas, la commutation est faite lorsque l'´ etat se trouve dans le bassin d'attraction du point d'´ equilibre ultérieur visé, nous avons développé une approche systématique traitant unprobì eme particulier dans le domaine de la commande non linéaire
