摘要
研究一类具有状态时滞的内联不确定性动态大系统的分散鲁棒 H∞ 控制问题 .系统的不确定性参数满足范数有界条件 .得到了由无记忆状态反馈分散控制器使每一个子系统和整个大系统都可镇定且满足给定 H∞ 性能的充分条件 .所得结果与系统时滞的大小有关 。
This paper deals with the problem of decentralized robust H∞ control for a class of interconnected uncertain dynamic systems with state delays. The parameter uncertainties are unknown but norm-bounded. A sufficient condition is obtained for making each subsystem and overall system stabilize and satisfy the given H∞ performance via linear memoryless state feedback decentralized controllers. The results are given in terms of linear matrix inequalities which depend on amount of the time delays.
