Fault Diagnosis of Some TV Seeker Based on General Grey Relation Analysis

摘要

Grey system theory has obvious advantage on handling "poor information and small sample data" problems. Some TV seeker's faults performance of such characteristics that the date is less and not integrity, and failure phenomenon is not explicit. So it comes to be difficult to diagnose the faults at the Basic level by a quick way. This paper means to build a model using the general gray relational analysis in order to establish contact between the fault parameter names and failure phenomenon. Then by using gray relational analysis on the fault records in the database and checking the model with another data. Calculation result shows that the method can judge fault position simply and quickly. The paper provides a kind of relatively reliable quantitative analysis basis for the fault diagnosis and locating faults.
