这份报纸与骚乱为分离时间延期系统建议柔韧的差错察觉和隔离(FDI ) 计划。FDI 计划不能仅仅检测而且孤立差错。上升方法被利用把分离时间延期系统转变成 non-time-delay 形式。一个概括结构化的剩余集合基于未知输入观察员(UIO ) 被设计。为每个剩余生成器，输入和相应致动器差错和骚乱表明的系统之一发信号被当作一个未知输入术语。剩余信号不能仅仅对骚乱是柔韧的，而且具有能力孤立致动器差错。建议方法被一个数字例子验证了。

英文摘要：

This paper proposes a robust fault detection and isolation （FDI） scheme for discrete time-delay system with disturbance. The FDI scheme can not only detect but also isolate the faults. The lifting method is exploited to transform the discrete time-delay system into the non-timedelay form. A generalized structured residual set is designed based on the unknown input observer （UIO）. For each residual generator, one of the system input signals together with the corresponding actuator fault and the disturbance signals are treated as an unknown input term. The residual signals can not only be robust against the disturbance, but also be of the capacity to isolate the actuator faults. The proposed method has been verified by a numerical example.
