基于模糊理论的飞机自动油门系统故障诊断方法

摘要

The aircraft auto-throttle system is one of the most important systems of aircraft, and its associated equipment is more and the operating logic is sophisticated, so it brings more convenience to the flight crew, but also increases the complexity and difficulty for fault test. Through fuzzy theory, combined with the working principle and the points of failure of aircraft auto-throttle system, this paper summed up a fault diagnosis technology combining with fuzzy theory and expert technology to automatically determine the cause of the fault of aircraft auto-throttle system.%飞机自动油门系统作为飞机上最重要的系统之一，其关联设备多并且工作逻辑复杂，在给飞行人员带来更多便利的同时，也加大了其故障测试的复杂性和困难度。本文通过应用模糊理论，并结合飞机自动油门系统的工作原理和故障点，总结出一种将模糊理论和专家技术相结合的故障诊断技术以自动判断飞机自动油门系统的故障原因。
