The delay-dependent robust stability criteria for neutral systems with mixed time-varying interval delays and nonlinear parameter perturbations are discussed. Based on the Lyapunov-Krasovskii functional approach and linear matrix inequality technology,some improved delay-dependent stability conditions are proposed by utilizing new integral equalities to deal with the bounding for the cross term. The criteria are derived in terms of linear matrix inequalities (LMIs). Compared to the existing criteria,the merit of the proposed conditions is less conservative. Numerical examples are given to illustrate the improvement on the conservatism of the delay bound over some reported results in the literatures.
