A New Delay-Dependent Stability Criterion for Uncertain 2-D Discrete Systems Described by Roesser Model Under the Influence of Quantization/Overflow Nonlinearities

摘要

This paper considers the problem of global asymptotic stability of a class of two-dimensional uncertain discrete systems described by the Roesser model under the influence of various combinations of quantization/overflow nonlinearities and interval-like time-varying delay in the state. The systems under consideration involve parameter uncertainties that are assumed to be deterministic and norm-bounded. A delay-dependent stability criterion is derived by estimating the forward difference of the Lyapunov functional based on the reciprocally convex approach. Examples are provided to illustrate the effectiveness of the proposed criterion.
