New Stability Analysis for Switched Neutral Systems

This paper is concerned with the stability for a class of switched uncertain neutral systems. The uncertainty is assumed to be of structured linear fractional from which includes the norm bounded uncertainty as a special case. Based on the property of completeness of systems, by using an improved Lyapunov-Krasovskii functional, a switching rule for the asymptotical stability of this systems is designed from the solution of linear matrix inequalities (LMIs). A numerical example is given to illustrate effectiveness of the result.
