Further results on descriptor time delayed system stability theory in the sense of Lyapunov: Pandolfi based approach

This paper gives sufficient conditions for the stability of linear singular discrete delay systems of the form Ex/spl dot/(t) = A/sub 0/x(t) + A/sub 1/x(t - /spl tau/). These new, delay-independent conditions are derived using approach based on Lyapunov's direct method. A numerical example has been working out to show the applicability of results derived. To the best knowledge of the authors, such result has not yet been reported.
