摘要 采用LMI方法,针对各个子系统研究一类由N个子系统构成且存在数值界不确定性关联大系统的分散鲁棒H∞控制问题。得到了由线性矩阵不等式给出的无记忆状态反馈分散鲁棒控制器,该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。该方法没有参数调整过程,求解应用方便,最后通过一个数值例子来说明该设计方法的有效性。 The problem of decentralized robust H∞ control for a class of interconnected uncertain dynamic large-scale systems composed of N subsystems is researched. The parameter uncertainties are unknown but value-bounded. A sufficient condition is obtained for each subsystem and overall system to be stabilizable and satisfies the given H∞ performance via linear memoryless state feedback decentralized controllers expressed in linear matrix inequalities. Finally a numerical example is given to demonstrate the effectiveness of the given approach.
