摘　　要：考虑了一类持续有界扰动下不确定时滞大系统的分散鲁棒镇定问题,通过构造lyapunov函数,利用线性矩阵不等式知识,提出了此类大系统可分散镇定的充分条件,通过求解一凸优化问题,给出具有较小反馈增益的分散稳定化状态反馈控制律的设计方法。最后通过一组数值算例证明了这种方法的有效性。The problem with the decentralized robust stabilization of a class of uncertain large-scale time-delay systems with bounded persistant disturbances is researched.By constructing Lyapunov functions,linear matrix inequality （LMI） is employed.A few sufficient conditions for such large-scale systems are derived.A convex optimization of LMI constraints is formulated to design a decentralized state feedback control with smaller gain parameters,which enables the closed-loop system to be asymptotically stable.The given example shows the method is effective.
