摘要

This paper investigates exponential stability of functional observer for a class of nonlinear systems with interval time-varying mixed delays. We first address the problem of functional observer design for nonlinear systems with interval time-varying mixed delays and establish the sufficient conditions of exponential stability of functional observer for this class of systems. Second, by utilizing Lyapunov-Krasovskii approach and some well-known inequalities, we convert the stability analysis problem into the feasible problem of several linear matrix inequalities (LMIs). We proposed sufficient conditions of the exponential stability of functional observer for nonlinear systems with interval time-varying mixed delays. Furthermore, the parameters of the delay-dependent observer are also designed using the Lyapunov-Krasovskii approach. Finally, we give two numerical examples and some simulation results to illustrate the effectiveness of the obtained method.
