| 摘 要： | 对线性多变量控制系统反馈矩阵增益约束元的选择问题，给出了一种鲁棒反馈矩阵零增益约束元选择的设计方法．该方法基于特征结构关于反馈矩阵增益元的灵敏度分析，将灵敏度相对较小的反馈矩阵元的增益取为零，不仅保持了鲁棒特征结构配置的优点，而且使设计的控制器结构简单．仿真结果表明，该方法是可行的．

| Abstract: | This paper presents an approach for choosing the gains that can be suppressed to zeros in the feedback gain matrix. This approach is based on the sensitivity of feedback gain with respect to the eigenstructure. So it not only guarantees robustness of the closed loop system but also simplifies the realization of the robust feedback controller. The simulation results demonstrate its effectiveness. |

| Keywords: | robust control eigenstructure assignment sensitivity gain constrained |
