| 摘 要： | 针对线性系统,基于线性矩阵不等式(LMI)给出了具有完整性的动态输出反馈控制器的设计方案,所得到的结论,不仅给出分别考虑执行器和传感器两类部件发生故障的完整性设计方案,而且给出了考虑执行器或传感器任何一类部件发生故障的完整性设计方案．本文使用了比离散故障模型更具有实际意义的连续故障模型．一个数值例子说明了所提方法的有效性．

| Abstract: | For linear system,a LMI (linear matrix inequality)-based approach is presented to design a dynamic out- put feedback controller for the closed-loop system to possess integrity,not only when sensor and actuator failure occurs seperately,but also when either actuator or sensor failure occurs.A more practical continuous model of sensor and actua- tor failures than discrete model is also considered.Finally,a numerical example is given to show the effectiveness of the obtained results. |
