For a class of stochastic state feedback systems, the state variance upper bound index consistent with pre specified circular pole index is discussed via linear matrix inequality (LMI) approach, a good range is given for variance upper bound index consistent with pre specified pole index.
该文对一类随机状态反馈系统 ,利用线性矩阵不等式 (LMI)方法 ,分析了闭环系统的、与约束圆形极点区相容的状态方差上界指标 ,得到了相容状态方差上界指标的较好取值范围 ,进而研究了相容极点区域与状态方差上界约束下 ,系统被控输出对扰动输入的H∞ 抑制界优化问题 ,给出了次优H∞ 抑制界和相应约束次优H∞ 控制。
