Sliding motion in discontinuous dynamical systems: periodic solutions, homoclinic connections, and nonlinear sliding modes

Abstract

This project aims to develop research in the field of nonsmooth differential equations. We are particularly interested in the sliding dynamics defined on the manifold of discontinuity. At a first moment, using the ideas from Melnikov, we study the bifurcation of a typical cycle of the Filippov systems. We also study the robustness of the chaotic behavior existing nearby a sliding Shilnikov orbit. We also track 1-parameters family of smooth vector fields approaching continuously to the discontinuous one and admitting an ordinary Shilnikov connection. Finally we consider the nonlinear sliding modes in discontinuous systems having the set of discontinuity as being algebraic varieties. (AU)
