This paper is concerned with a class of nonlinear uncertain switched networks with discrete time-varying delays . Based on the strictly complete property of the matrices system and the delay-decomposing approach, exploiting a new Lyapunov-Krasovskii functional decomposing the delays in integral terms, the switching rule depending on the state of the network is designed. Moreover, by piecewise delay method, discussing the Lyapunov functional in every different subintervals, some new delay-dependent robust stability criteria are derived in terms of linear matrix inequalities, which lead to much less conservative results than those in the existing references and improve previous results. Finally, an illustrative example is given to demonstrate the validity of the theoretical results.
本文研究了一类具有离散时变时滞的非线性不确定切换网络。基于矩阵系统的严格完备性和时滞分解方法,利用新的李雅普诺夫-克拉索夫斯基泛函将时滞分解为积分项,设计了依赖于网络状态的切换规则。此外,通过分段时滞方法,在每个不同的子区间内讨论李雅普诺夫函数,得到了一些新的时滞相关鲁棒稳定性判据,这些判据以线性矩阵不等式的形式给出,与已有文献中的结果相比,具有更小的保守性,并改进了已有结果。最后,通过一个实例验证了理论结果的有效性。
