Absolute stability and Lyapunov-Krasovskii functionals for switched nonlinear systems with time-delay

摘要

We derive conditions for the existence of Lyapunov-Krasovskii functionals for a number of classes of nonlinear switched systems with time-delay. In particular, we first give conditions for systems of retarded type that relax those recently described in Sun and Wang (2013). Using similar techniques, related results are then derived for coupled differential-difference systems and for systems of neutral type. Finally, we briefly note some corresponding results for discrete-time systems.
