摘　　要：对一类具有数值界不确定性的关联时滞大系统,应用线性矩阵不等式(LMI)方法研究使其分散稳定化的鲁棒控制器设计问题。通过引入一种线性状态变换,分离出时滞依赖因子。在此基础上给出其存在分散鲁棒稳定化控制器的充分条件。The design of decentrained robust stabilization controller for large-scale uncertain time delay systems by means of linear matrix inequality（LMI） approach is studied. A new linear state transformation is proposed to sep- arate the delay-dependent factors out. A sufficient condition for the existence of decentralized stabilization control laws is derived.
