Stabilization of a class of slow–fast control systems at non-hyperbolic points

Abstract: In this paper we study the stabilization problem of a general class of slow-fast systems with one fast and arbitrarily many slow states. Moreover, the class of systems under study is slowly actuated, meaning that only the slow states are subject to the action of a controller. Furthermore, we are particularly interested in the case where normal hyperbolicity is lost. We show that by using the Geometric Desingularization method, it is possible to design controllers to locally stabilize non-hyperbolic points of a… Show more

“…To overcome this, we shall show that it is possible to "inject" a normally hyperbolic behavior to the fast variable through the backstepping algorithm [12]. • A general treatment of a more general class of SFSs around a fold point shall be presented in [6]. Our main contribution is as follows.…”

“…We now examine the concept of a folded critical manifold, determine the conditions needed to prove its existence, and then apply these ideas to our specific critical manifold S c . The discussion of geometric singular perturbation theory presented in [36,11] covers fold points of critical manifolds in some detail.…”
