Research on Fault Diagnosis of Diesel Engine's Air Valve Based on Rough Sets Theory
Bang Zhang · Transactions of Csice · 2002
On the basis of ANN fault diagnosis system of internal combustion engine,rough sets theory is introduced,and its application in characterized paramaters attribute optimization is explored too.The discernibility matrix algorithm is used to reduce attributes in decision table.The unnecessary attributes are eliminated.The inner redundancy of fault diagnosis systems condition attributes is revealed.And the complexity of neural networks structure is also decreased.The result of attribute reduction is given finally.
