研究了具Ｌ２有界不确定性系统鲁棒最优设计（ＬＱＬ）中满足极点约束的加权阵的选取问题．首先建立鲁棒最优极点配置区域，然后给出加权阵的构造性公式，实现了一定稳定裕度下的鲁棒性优化设计．最后举例说明该方法的有效性．
This paper studies the selection of weighted matrices that satisfy the pole constraints in the robust optimal design (LQL) of systems with L2 uncertainties. Firstly, a robust optimal pole configuration area is established, and then a constructive formula of the weighted array is given, and a robust optimization design with a certain stability margin is achieved. The last example illustrates the effectiveness of this method.
