摘要
本文论述了现代电传飞控的故障检测系统,介绍了典型的现代电传飞控系统的组成与技术特点。设计了基于专家系统的故障检测系统,专家系统由综合数据库、故障知识库、推理机、知识获取以及决策解释等组成。依据专家系统的原理建立了电传飞控系统的故障综合数据库与故障知识库,采用正向和逆向推理原理完成了推理机的策略设计,针对飞控系统高安全性要求,提出综合数据库的初始数据与检测方法以硬软件的形式驻留于飞控系统之中,故障知识库与推理策略在独立于飞控系统的故障检测系统中。本文对电传飞控系统的故障检测的实现有一定的实用性和推广价值。
This paper discussed fault detection system for modern Fly-By-Wire System, introduced an classic structure and technology features of modern Fly-By-Wire System. Author have designed fault detection system which was based on expert system, that included integrated data base, fault knowledge base, reasoning machine, knowledge acquisition and explain decision etc. Integrated data base and fault knowledge base of Fly-By-Wire System were based on expert system, the strategy of reasoning machine have adopted certainty reasoning, which included forward reasoning and backward reasoning. Based on high security requirements of Fly-By-Wire System, initial data and detection method of integrated data base consist in Fly-By-Wire System in the form of software and hardware, fault knowledge base and reasoning machine consist in fault detection system. This paper is of value in fault detection of Fly-By-Wire System.
