| 摘 要： | 对一类线性离散随机系统的控制问题，研究两类约束指标：圆形极点区域与状态方差上界的相容性，并对同时具有上述两类相容约束的控制问题，给出求取满意控制策略的有效方法，利用线性矩阵不等式（ＬＭＩ）方法，得到了与指定极点区域相容的状态方差上界指标的较好取值范围。算例说明了所得研究成果。

| Abstract: | The consistency of
constraint indices of circular pol e and statevariance upper bound is studied for a class
of discrete-time stochas tic systems via state feedback control,and satisfactory strategy
method is provi ded for the control systems with two kinds of consistent constraint
indices abov e.By using linear matrix inequality (LMI) approach,a good region is presented
fo r the upper bound index of state variance which is consistent with the prespecif ied
pole region.An example illustrates the results obtained in this paper. |
