COMPARATIVE STUDY OF SOME FAULT DIAGNOSTIC TECHNIQUES

摘要

The paper presents experimental study on some approaches for Fault Detection and Isolation (FDI) in linear systems. Three families of model-based methods were used: Generalized Observers Scheme (GOS), Dedicated Observers Scheme (DOS) and methods based on the likelihood ratio. The purpose of this study is to pursue quantitative FDI methods to spacecraft systems as complementary approaches to the qualitative methods adopted by NASA.
