Design of fault diagnosis of diesel engine system based on rough set theory
Jun Liu · Jisuanji gongcheng yu sheji · 2008
A program is designed based on arithmetic of rough set theory for decision-rule extracting and parameter reduct in fault infor-mation table of engine.First,the fault information of diesel power equipment is reducted.Then,rules are determined.Inference engine is achieved by positive inference and correlating control strategy,which would complete the inference operation in fault diagnosis system.It is very efficiency that rough set reduct and rule extract based our program.The inference time is reduced,and the work efficiency is enhanced.
