Abstract:

This paper summarizes the methods on fault detection and diagnosiswhich is very important for condition monitoring of LRE.The methods on fault detection and diagnosis applied in LRE system are classified into a few groups and got disscussed in details.Some problems being worthy particularly of attention are presented.Finally,it is pointed out that a few key tasks must be improved and studied further.Meanwhile,the further development on this technique is also discussed.
