基于模型的航天器推进系统故障诊断

本文设计了基于模型的推进系统的故障诊断系统。根据推进系统的结构和行为模型，分析出各组件所处的工作状态及组件之间的连接关系，利用JMPL建模语言建立了推进系统各组件的定性模型。把推进系统模型和系统场景文件输入给诊断推理引擎，可实现推进系统的实时诊断。诊断结果表明，建立的推进系统模型是准确可靠的，开发的诊断系统能有效地找出故障组件并确定故障组件的状态。

Model-based Fault Diagnosis System for Spacecraft Propulsion System

This paper designed a model-based fault diagnosis system for spacecraft propulsion system.Based on the architecture and behavior model of the propulsion system,this paper analyzed the working states of components and connections between the components.The working model of the propulsion system was built with JMPL model language.The reasoning engine took the system model and the real time scenarios as inputs,then the monitoring and diagnosis of the propulsion system could be achieved.The results proved that ...
