摘　　要：研究含混合常时滞的不确定中立系统的鲁棒稳定性问题,基于时滞分割方法,分别通过构造恰当的Lyapunov-Krasovskii泛函,并结合积分不等式处理技巧、自由权矩阵以及凸组合技术得到新的稳定性判据.通过数值仿真,将文中所得结论与已有的文献结果进行比较,验证结论的有效性.数值仿真表明:文中方法改善了已有文献的结果,降低了结论的保守性.The robust stability of uncertain neutral system with interval time-varying delay is studied.The new stability criteria are obtained by constructing appropriate Lyapunov-Krasovskii functional and combining integral inequality handling techniques,free weight matrix and convex combination.Numerical simulations are given to show the effectiveness of the proposed approach and the results of this paper are compared with the existing cited results.It shows that the method proposed in this paper improves the known results and shows less conservatism.
