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,并 以线性矩阵不等式的形式给出.Abstract: 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 each subsystem and overall system to be stabilizable and satisfy the given H∞ performance via linear memoryless state feedback decentralized controllers. The re- suits depend on the size of the delays and are given in terms of linear matrix inequalities.
