Review of multiple fault diagnosis methods
Kaicheng Zhang · Control theory & applications · 2015
Multiple fault diagnosis(MFD) is a key issue in fault diagnosis technology,because multiple fault commonly exists in engineering and complex systems.We give a survey on fault mechanism,manifestation of symptoms,and approach thinking for MFD.Problem-solving on possible multiple output in fault mode identification is defined as a scientific problem of MFD.Difficulties for MFD is analyzed,and the research status of MFD is discussed.Meanwhile,all typical diagnosis methods and relevant technologies in the discussion are classified into three categories,i.e.,analytical model-based approaches,qualitative knowledge-based approaches,and data-driven-based approaches.Advantages,disadvantages,and scopes of these methods and technologies are separately listed;research directions for MFD are mentioned.
