A Razumikhin approach for the incremental stability of delayed nonlinear systems - Chaillet, Antoine; Yu. Pogromsky, Alexander; Rüffer, Björn S. (Proc. 52nd IEEE Conf. Decis. Control, 2013)
This paper provides sufficient conditions for the incremental stability of time-delayed nonlinear systems. It relies on the Razumikhin-Lyapunov approach, which consists in invoking small-gain arguments by treating the delayed state as a feedback perturbation. The results are valid for multiple delays, as well as bounded time-varying delays. We provide conditions under which the limit solution of a time-delayed nonlinear system to a periodic (resp. constant) input is itself periodic and of the same period (resp. constant). As an illustration, a specific focus is given on a class of delayed Lur’e systems.
