| 摘 要： | 利用Lyapunov-Krasovskii泛函方法对中立型变时滞系统的时滞相关鲁棒稳定性问题进行了分析。通过在新构建的Lyapunov-Krasovskii泛函的导数中恰当地引入零项，并且对泛函导数中的d（t）项进了新的界定，获得中立型变时滞系统的时滞相关稳定性条件。数值实例表明：采用所提方法得到的结果相比已有文献结果，具有更小的保守性。

| Abstract: | The delay-dependent robust stability for neutral systems with time-varying delay is analyzed by means of the Lyapunov-Krasovskii functional method. A new delay-dependent stability sufficient condition is obtained by introducing some zero-item in the derivative of the Lyapunov-Krasovskii functional and employing new bounding technique for . The numerical examples show that the result of the proposed method has less conservative comparing to the existing result. |
