摘　　要：介绍一种基于区间观测器的故障诊断技术.为突出区间观测器在故障诊断方面的优势,总结归纳针对不同类型系统构造的可以达到故障诊断目的的区间观测器,并讨论观测器的设计条件.例如,事件触发机制下的故障检测区间观测器,针对线性参数变化系统设计的基于区间观测器的故障检测机制,在区间观测器的框架下实现带有未知互联项的T-S模糊大系统的故障隔离,以及利用区间观测器对多智能体系统实现故障隔离.最后探讨该领域亟待解决的问题.The purpose of this survey is to introduce a novel interval observer based fault diagnosis technique. We particularly summarize various interval observers for different systems and discuss design conditions. For example, the event-triggered fault detection method based on interval observers, the parameter-dependent interval observer based fault detection scheme for linear parameter-varying systems, the fault isolation method for T-S fuzzy interconnected systems with unknown interconnections by using interval observers, as well as the interval observer based fault isolation method for discrete-time multi-agent systems. The common goal of discussion on these topics is to highlight the advantages of the interval observer based fault diagnosis schemes. Finally, some open problems in the field are pointed out.
