Abstract : "In this paper, we focus on the problem of the absolute and robustly absolute stability for the neutraltype
Lur’e system with time-varying delay. By combining the piecewise analysis theory with extended doubleintegral
and Wirtinger-based inequalities technology, some new delay-dependent stability criteria for the absolute
and robustly absolute stability are proposed via Lyapunov-Krasovskii functional (LKF) approach. The stability
conditions can be expressed as convex linear matrix inequality (LMI) framework, which can be solved by using
standard LMI convex optimization solvers. The criteria proposed in this paper are less conservative than some
previous ones. Finally, some numerical examples are presented to show the effectiveness of the proposed approach."
