Analysis Methods of Failure Model for LRE
LRE is a very complicated system working under severe environment and the requirement for the system is very high. Therefore, it is necessary to research the fault analysis, detection, and diagnosis. Fault analysis, especially the fault phenomenon, mode, and mechanism of the analysis, is the basis of fault detection and diagnosis. There are mainly three kinds of methods for the fault analysis. As the most basic method, the first one is to accumulate all kinds of fault phenomenon and patterns and analyze the reason based on the ground test. However, it is impossible to get a complete fault connotation due to the limited number of tests.
