| 摘 要： | 研究了具有串联结构的线性不确定系统的鲁棒容错控制问题．针对执行器失效故障，证明了对于两级串联结构的线性系统，可分别设计两个单级状态反馈容错控制器，通过求解两个Riccati不等式，得到整个系统的容错控制器．用该方法设计的闭环系统，在执行器发生故障时具有完整性，而且，对于系统的参数不确定性具有鲁棒性．

| Abstract: | The robust fault-tolerant control for a type of linear cascaded uncertain systems is studied. It is proved that the fault-tolerant controller for the whole system can be designed by solving two Riccati inequalities through designing respectively two mono state feedback fault-tolerant controllers for the cascaded linear system against actuator failures. The closed-loop systems based on this method possess integrity in the case of actuator failures as well as robustness in the presence of parameter uncertainties. |
