摘要
燃油系统作为飞机不可或缺的功能和保障系统,对飞机的飞行安全有着重大影响。传统故障诊断方法已经不能满足日益复杂的燃油系统诊断和维护需求。基于模型诊断是为了克服传统诊断方法的缺点而兴起的一项新型的智能推理诊断技术。研究了基于模型的飞机燃油系统故障诊断方法,建立了故障诊断模型,给出了基于模型的燃油系统故障诊断推理策略。设计并实现了基于模型的燃油系统故障诊断系统,并通过诊断实例进行了验证。
The fuel system is an indispensable function and support system of aircraft.It has a significant impact for the flight safety.Thus,the traditional fault-diagnosis methods can not satisfy needs of diagnosis and maintenance of the increasingly complicated fuel system.Model-based diagnosis（MBD） is a new type of intelligent reasoning and diagnosis technology for overcoming the shortcomings of the traditional fault diagnosis technique.The fault diagnosis technique for the model-based civil aircraft fuel system is discussed.The diagnosis models are constructed.The diagnosis reasoning strategy is proposed.The fault diagnosis system for the model-based fuel system is designed and developed,and a demonstration diagnosis result is given.
