Design of Fault Diagnosis Expert System for UAV Flight Control System

针对无人机飞控系统的特点和维护要求，本文介绍了MBIT故障诊断专家系统的设计思路和实现方法，构建了无人机飞控系统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，组建综合数据库和故障解释等问题。并结合某型号给出了具体的示例。在工程实际应用过程中，可以利用本系统对无人机飞控系统进行有效维护。

Aiming at Unmanned Aerial Vehicle （UAV） flight control system＇s characteristics and maintenance requirements, the design thinking and implementation method of MBIT fault diagnosis expert system are introduced, the architecture of the fault diagnosis expert system for UAV flight control system is structured and the issues of establishing the fault knowledge base, formulating the inference mechanism and building the synthesis database as well as fault explanation are lueubrated in this paper. And a specific demonstration is given based on a certain project. The fault diagnosis expert system can be used for maintaining UAV flight control system effectively in the process of practical engineering application.
