摘　　要：针对一类具有非匹配不确定性的离散时滞复杂系统,利用极点配置方法设计了渐近稳定的滑模面,并在此基础上设计了变结构控制器,此过程不再要求系统不确定性满足匹配条件.最后通过仿真算例说明了该方法的有效性.An asymptotically stable sliding mode surface has been designed for a class of uncertain discrete-time complex large-scale systems with unmatched uncertainty and delays by using the pole assignment approach.The variable structure controller is designed subsequently.The matched uncertainty have not been needed in this design approach.Finally,a numerical example is given to illustrate the feasibility of the proposed design approach.
