摘要
目的研究不确定微分中立系统带有时变时滞的稳定性问题,所考虑的系统带有时变结构不确定项和时变时滞。方法采用Lyapunov-Krasovskii泛函理论和线性矩阵不等式(LMI)。结果导出该系统时滞依赖渐近稳定性条件。结论用一个数值算例来说明此方法的可行性以及更低的保守性。
Aim To study the stability criterion for uncertain neutral delay differential systems with time delays, the systems under consideration have variable structure with uncertainties and time- varying delay at times. Methods Lyapunov functional and Linear Matrix Inequality（LMI） are adopted. Results It was proved that a delay-dependent criterion for asymptotic stability. Conclusion Numerical examples show the effectiveness of our result and much less conservation.
