| 摘 要： | 研究了线性不确定系统区域极点与状态方差约束下的动态输出反馈可靠控制器的设计问题．首先在连续型执行器故障模型下，利用线性矩阵不等式方法，建立了容错控制中区域极点指标与方差上界指标间的相容性理论；然后，应用极值原理分析了与区域极点指标相容的方差上界指标的取值范围；最后，给出了同时满足区域极点与状态方差约束下的动态输出反馈可靠控制器的设计步骤．仿真实例验证了结果的有效性． |
| 关 键 词： | 容错控制 执行器故障 区域极点 状态方差 相容性 |

| Abstract: | The problem of dynamic output feedback reliable controller design for linear uncertain systems is discussed. A continuous gain actuator failure model is adopted. Based on the linear matrix inequality approach, the consistency theory between regional pole index and steady state variance index is setted up. The extremum theory is adopted to analyze the range of state variance indices in detail which is consistent with regional pole. The effective reliable controller design steps are provided with consistent indices constraint. A simulation example shows the effectiveness of the design method. |
| Keywords: | Fault tolerant control Actuator failures Regional pole State variance Consistency |
