Improved Stability Result for Discrete-time Systems with Saturation Nonlinearities and Time-varying Delay

摘要

This paper presents the criterion for the asymptotic stability of delayed discrete-time systems exerting parameter uncertainties and saturation overflow nonlinearities. With the utility of an augmented Lyapunov-Krasovskii functional and a more relaxed bounding technique, delay-dependent criterion is established. The potential capability of the proposed approach is then demonstrated by comparing with the existing approaches. Numerical examples show the efficacy of the presented criterion.
