摘要
讨论了一类具有非线性扰动的中立型不确定时滞系统的鲁棒稳定性问题.基于增广的Lyapunov-Krasovskii泛函和自由权矩阵的方法,推导出一个以线性矩阵不等式形式给出的时滞相关稳定性的充分条件.最后通过一个数值算例说明了结果的有效性以及较已有工作的改进.
The robust stability criteria for a class of neutral uncertainty delayed systems with nonlinear perturbation are discussed.Based on the augmented Lyapunov-Krasovskii functional and the free-weighting matrix method,a sufficient condition of delay-dependent stability expressed in terms of linear matrix inequalities is obtained. Finally, a numerical example is provided to show the effectiveness of the results and the improvement over the existing results.
