摘要
In this paper, we focus on the problem of the absolute and robust absolute stability for time-delayed Lur'e systems. Both the cases with time-invariant and time-varying nonlinearities are considered. By using two improved relaxed integral inequality lemmas, new delay-dependent absolute and robust absolute stability criteria 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.
