摘　　要：考虑了一类不确定广义组合大系统,利用Lyapunov稳定性理论和矩阵范数性质研究了该类系统的分散镇定问题.给出了一种分散输出反馈鲁棒镇定控制器的设计,得到了系统可输出反馈鲁棒镇定的不确定量的范数界.同时分析了广义组合大系统及各个孤立子系统的脉冲控制问题,给出了其闭环系统无脉冲的不确定量的范数界.最后获得了广义组合大系统及各个孤立子系统的闭环系统同时渐近稳定和无脉冲的范数界.This paper considers a class of uncertain generalized large-scale composite system and studies the decentralized stabilization problem for the system by employing Lyapunov method and using the matrix norm properties. We design a kind of decentralized output feedback robust controllers and obtain the norm bounds of system uncertainties which ensure robust stabilization for the system. Meanwhile, we analyse the impulse control problem of uncertain generalized composite system and its isolated subsystems. We give the norm bounds of system uncertainties which ensure the closed loop system impulse free. Finally, we obtain the norm bounds of being asymptoticly stable and impulse free for the closed loop of uncertain generalized composite system and its isolated subsystems.
