Abstract : "Two recent Lyapunov-based methods: delay-partitioning approach and Jensen inequality approach, have
reduced the conservatism and the complexity of the stability result for one-dimensional (1-D) time-delay systems,
respectively. This paper concerns the analysis of delay-dependent stability for two-dimensional (2-D) discrete
systems with interval time-varying delays. By applying a delay partitioning-based Lyapunov function combining
with the approaches of 2-D Jensen inequalities, a new delay-dependent stability criterion is derived in terms of
linear matrix inequality (LMI). In addition to delay dependence, the obtained criterion is also dependent on the
partition size. It is rigorously proved that the authors’ result reduces the conservativeness and computational burden
than some recent ones. Numerical examples show the effectiveness and advantage of our result."
