The H_∞ filtering problem for interconnected systems is addressed in this paper. In order to facilitate the stability analysis of interconnected systems under the conditions of failed interconnections, a strategy related to switched systems is introduced. Assume that the interconnections among these subsystems disconnect based on the mode‐dependent average dwell time (MDADT), a switching signal is implemented to denote the failed interconnections cases. In the aid of the MDADT method, a filter is designed such that the fault detection (FD) system is asymptotically stable and satisfies the weighted H_∞ performance. Finally, a numerical simulation is provided to show the effectiveness of the proposed filter.

互连失效的离散时间互连系统的H∞滤波

的ħ _∞用于互连系统过滤问题在本文中被寻址。为了便于在互连失败的情况下对互连系统进行稳定性分析，引入了与交换系统有关的策略。假设这些子系统之间的互连根据与模式有关的平均驻留时间（MDADT）断开，则将使用一个切换信号来表示发生故障的互连情况。在MDADT方法的帮助下，过滤器被设计为使得故障检测（FD）系统是渐近稳定的，并且满足加权ħ _∞性能。最后，提供了数值模拟，以显示所提出的滤波器的有效性。
