The Fault Diagnosis of Mechanical and Electrical Products Based on Dimension Reduction in Universal Space
Shi Gang · Journal of Shanghai Institute of Technology · 2011
This paper presents a fault diagnosis method of mechanical and electrical products based on dimension reduction in universal space.The computation complexity was greatly reduced by decreasing the dimensions of universe space of Rough Set.Brief and useful decision rules were extracted through attributes reduction and value reduction.The paper used this method to diagnose faults on product line of electronic ballasts,the real case analysis showed this new method could improve the ability of fault diagnosis and will be useful in online fault diagnosis.
