摘　　要：讨论了一类区间离散时滞广义系统的鲁棒稳定性问题,在给出区间离散时滞广义系统的等价描述之后,基于系统参数矩阵不等式,分别得出了时滞独立和时滞依赖情况下区间离散广义系统稳定的充分条件,数值例子说明了该方法的有效性.The problem of robust stability for a class of interval discrete time-delay singular systems is discussed.Firstly,a kind of equivalent description of the interval discrete time-delay singular systems is given.Then sufficient conditions for robust statility of interval discrete-time singular systems for timeidelay independent and time-delay dependent are obtained in terms of matrix inequalities.Finally,a numerical example is given to demonstrate the effectiveness of the proposed method.
