Delay-dependent stability analysis for neutral systems with equivalent delays

This paper is concerned with the delay-dependent stability and robust stability for uncertain neutral systems with equivalent delays. Through constructing a new form of Lyapunov-Krasovskii functional, using slack matrices and integral inequality, the delay-dependent stability criteria are derived in terms of linear matrix inequalities. Numerical examples are given to illustrate the improvement on the conservatism of the delay bound over some existing results.
