This paper deals with the problem of the robustly absolute stability for neutral-type Lur'e systems with mixed time-varying delay. By combining the piecewise analysis theory with the reciprocally convex method and Wirtinger-based inequality technology, some new delay-dependent stability criteria are proposed via a modified Lyapunov-Krasovskii functional (LKF) approach. The stability conditions can be solved by using standard linear matrix inequality (LMI) convex optimization solvers. The criteria are less conservative than some previous ones. Three numerical examples are presented to show the effectiveness of the proposed approach.
