The invention discloses an observer-based distributed fault detection method for an aircraft system, and belongs to the technical field of fault detection. A CPS architecture is applied in the field of aircraft system fault detection, the influence among subsystems is fully considered, and certain valuable new thoughts and examples are provided for promoting the progress of an aircraft system fault processing technology; an aircraft system is essentially hierarchical, large-scale and complex, and the internal relation of the system is complex, so that a single-system model is difficult to fully describe the characteristics of the aircraft system. Compared with the prior art, the interconnected large system model adopted by the method is more suitable for describing an aircraft system. In addition, in order to describe more performance characteristics of the aircraft system and enable the system model to be more general, a generalized system model is adopted.
基于观测器的飞机系统分散式故障检测方法,属于故障检测技术领域。在飞机系统故障检测领域应用CPS架构,充分考虑各子系统之间的影响,为推进飞机系统故障处理技术的进步提供了一定有价值的新思路和范例;由于飞机系统本质上具有层次性、规模性和复杂性,系统内部联系错综复杂,因此单系统模型很难充分描述其特性。相比之下,本发明所采用的互联大系统模型更加适合描述飞机系统。此外,为了描述飞机系统的更多性能特征并且使得系统模型更具一般性,本发明采用了广义系统模型。
