摘　　要：针对电传飞控系统的特点和维护性要求,介绍了MBIT故障诊断专家系统的设计思路及实现方法。阐述了MBIT的功能与用途。构建了电传飞控系统MBIT故障诊断专家系统的体系结构,深入研究了如何建立故障知识库、制定推理机制、组建综合数据库和决策解释,并结合某型号,给出了具体的示例。工程实际使用过程中,利用本系统可以全面地对电传飞控系统进行有效的维护。Aimed at fly-by-wire control system＇ s characteristic and demand of maintenance, the design ideal and realization method of maintenance built-in-test fault diagnosis expert system are introduced. Function and purpose of MBIT are expounded. The configuration of FBW control system MBIT fault diagnosis expert system is constructed, how to establish fault repository and constitute consequence mechanism and establish integration database and explain decision-making process are lucubrated, some material illustrations are given based on a certain project mission. Using this fault diagnosis expert system could afford all-around and effective maintenance to FBW control system in engineering application.
