Abstract: A framework to establish input-to-state stability (ISS) of nonlinear dynamical systems, which possess multiple invariant solutions (equilibria, limit cycles, etc.), is introduced. First, an extension of the conventional Lyapunov theory is given. Second, for state-periodic systems the conditions are relaxed and formulated via a sign-indefinite function with sign-definite derivative. The new result is established by using the framework of Leonov's cell structure.
Bio: Denis Efimov received Ph.D. degree in Automatic Control from the Saint-Petersburg State Electrical Engineering University (Russia) in 2001, and Dr.Sc. degree in Automatic control in 2006 from the Institute for Problems of Mechanical Engineering RAS (Saint-Petersburg, Russia). From 2006 to 2011 he was working in the L2S CNRS (Supelec, France), the Montefiore Institute (University of Liege, Belgium) and IMS CNRS lab (University of Bordeaux, France). In 2011, he joined Inria (Lille - Nord Europe center). Starting from 2018 he is the scientific head of Valse team. He is a member of several IFAC TCs and a Senior Member of IEEE. He is also serving as an Associate Editor for IEEE Transactions on Automatic Control, IFAC Journal on Nonlinear Analysis: Hybrid Systems and Asian Journal of Control.
