Dynamical Output Feedback Controller for Uncertain Continuous-Time Time-Delay Systems Containing Saturating Actuator

Abstract

This paper investigates the problem of the stabilization of uncertain time-delay systems containing saturating actuators. These uncertainties may be linear, nonlinear, and/or time-varying, but only the upper norm-bounds are known. The Lyapunov-Krasovskii technique is employed to analyze the stability robustness for the uncertain closed-loop system which is based on dynamical output feedbak controller. Some sufficient criteria addressing the robust stabilization of such systems are proposed. These conditions are shown to be an extention of those given by Han et al. (1998c) which are less restrictive than those given by Han and Mehdi (1998b) and Su et al.(1989).
