Delay-dependent stability criteria for uncertain neutral systems with time-varying delay

This paper focuses the problem of delay-dependent stability criteria for a class of time-varying discrete delay neutral systems with time-varying structured uncertainties. A sufficient condition for discrete delay-dependent and neutral delay-independent stability is derived in the terms of the solutions of linear matrix inequality. The new criteria consider the information contained in the nominal system equation itself. Numerical examples are given to indicate that these criteria are effective and have a significant improvement over some previous results.
