摘　　要：考虑了带有时滞的离散不确定系统的鲁棒D-稳定化问题,利用矩阵范数理论给出了系统稳定的充分条件,进而推广了该文的结果.对两类给定结构的控制器,得到了相应的不确定的离散闭环系统的鲁棒D-稳定的充分条件.基于这些条件,给出了相应的鲁棒D-稳定化控制器的设计方法,并举例说明了提出的方法的有效性.The problem of robust D - stabilization for uncertain discrete - time system with delay is considered. The sufficient condition of stability is obtained, making use of the norm theory. These condi- tions obtained in this paper is extended, For two classes of controllers with given structure, the sufficient conditions for robust D - stabilization of uncertain discrete timedelay systems are derived. Based on these conditions, the design procedures of robust D - stabilizing controllers are developed. A numerial example is given to illustrate the applicability of the methods.
