研究了一类离散切换时滞系统的稳定性分析问题。利用新构造的李雅普诺夫泛函和平均驻留时间方法，得到了系统指数稳定的时滞相关充分条件。所得到的结果提供了一个解决方案的基本问题之一，在离散时间切换时滞系统，即，找到一个切换信号的切换时滞系统是指数稳定的。最后通过两个算例验证了所得结果的有效性.
The stability analysis problem is studied in this paper for a class of discrete-time switched time-delay systems. By using a newly constructed Lyapunov functional and the average dwell time scheme, a delay-dependent sufficient condition is derived for the considered system to be exponentially stable. The obtained results provide a solution to one of the basic problems in discrete-time switched time-delay systems, that is, to find a switching signal for which the switched time-delay system is exponentially stable. Two illustrative examples are given to demonstrate the effectiveness of the proposed results.
