New delay-dependent stabilization result for linear time-delay system with actuator saturation

Abstract

In this communication, a modified delay-dependent stabilization criterion is derived based on new Lyapunov-Krasovskii functional for ascertaining local stabilization of an open-loop unstable time-system subjected to actuator saturation, while approximating the saturation function using polytopic representation. A numerical example is considered to show that the proposed criterion yields less conservative results compared to the existing ones in terms of delay upper bound and domain of attraction (DOA) estimation.
