Non-uniform stabilization of control systems
1 Department of Mathematics, National Technical University of Athens, Zografou Campus, 15780, Athens, Greece
Aversion of non-uniform in time robust global asymptotic stability is proposed and enables us to derive: (1) sufficient conditions for the stabilization of uncertain nonlinear triangular time-varying control systems; (2) sufficient conditions for the solution of the partial-state global stabilization problem for autonomous systems. The results are obtained via the method of integrator backstepping and are generalizations of the existing corresponding results in the literature.
Keywords: integrator backstepping; time-varying feedback; time-varying systems.
