AI总结:

提出一种基于模型的多故障诊断工具,利用因果图技术进行检测与定位,并通过键合图建模描述变量间的因果关系,实验对比了因果图方法与经典AI和FDI方法的性能。

摘要:

本文提出了一种基于模型的多故障诊断工具,其检测与定位技术借鉴了人工智能和自动控制领域的方法。集成到监控系统中的诊断过程必须具有解释性特征。基于因果推理的技术是达到此目的的一种有效方法。使用键合图建模来描述过程变量之间的因果关系。为了比较因果图技术与经典人工智能(DX)和控制理论(FDI)方法的性能,展示并讨论了实验结果。

英文摘要:

This work proposes to put up a tool for diagnosing multi faults based on model using techniques of detection and localization inspired from the community of artificial intelligence and that of automatic. The diagnostic procedure to be integrated into the supervisory system must therefore be provided with explanatory features. Techniques based on causal reasoning are a pertinent approach for this purpose. Bond graph modeling is used to describe the cause effect relationship between process variables. Experimental results are presented and discussed in order to compare performance of causal graph technique and classic methods inspired from artificial intelligence (DX) and control theory (FDI).
