Based on Rough Sets Theory Aeroengine Suspension Fault Diagnosis
HU Jia-lin · Failure Analysis and Prevention · 2010
Because of the imperfection and inaccuracy of the fault information from fault sites,the rough set theory is often used to deal with the imperfection and inaccuracy of the information.According to the information on aeroengine rotary speed suspension faults,and based on the rough set theory,the common features of the faults were abstracted,and a decision table was established.Then the decision table was simplified,according to which a diagnosis rule database for aeroengine suspension defaults was established.Based on two suspension fault cases,the diagnosis rule database was validated,and it proved to be effective.
