Abstract设计了基于模型的电源故障诊断原型。它由电源各器件的正常工作模型,故障模型,冲突求解模块,HS树生成和修剪模块,故障信息报告和故障模式识别模块等组成。利用电源系统正常工作模型,实现了故障定位隔离功能。论证了仅仅使用正常工作器件就可以推理出诊断解中各个故障器件的参数值,将这些参数和故障模型相比较,能够识别故障模式。诊断结果表明本文能有效地进行故障定位并能识别故障模式。
Other AbstractA model based diagnosis engine for spacecraft power system is introduced. The diagnosis engine is composed of power system components’normal structure and behaviormodels, faultmodels, a confilct sets solution module, a HS tree generating and p runing module, a fault information reporting module, and a fault mode identification module. The engine can isolate fault components by using Reiter’s theory of diagnosis form components’normal structure and behaviormodels. It is p roved that if only normal components are used, the engine could obtain abnormal components’input and output values. Using these information and fault models of components, the engine can identify the faultmodes of abnormal components.
