基于时空结构的卫星智能诊断模型研究

针对卫星这类复杂系统的故障诊断,提出了基于时空结构的智能故障诊断系统模型(iFDS),从系统结构,结构模型,推理机制、流程模型等方面进行论述,通过对各种故障诊断方法进行融合,实现了卫星系统网络化、个性化、远程并行诊断的智能故障诊断.在故障推理机制研究中,将故障分为系统故障、多发故障和单元故障3类,分别对每一类故障提出相应的智能故障推理方法.

Research for Intelligent Diagnosis Model of Satellite Based on Space-time Structure

Satellite-oriented model of intelligent failure diagnosis system based on space-time structure(iFDS) is proposed.The model framework,inference rules and flow of iFDS are all discussed so as to put individuation and characteristics of network,telecommuting and concurrent into effect by means of integration of various technologies on failure diagnosis.In the research to inference rule of iFDS,the failures are classified into 3 groups: system failure,frequent failure and unitary failure,and the intellectualized methods of failure inference corresponding respectively to the failure groups above are presented.
