The Study of Aircraft Fuel System Real-Time Fault Diagnosis Using Expert Systems

For the problem of fault diagnosis of aircraft fuel system,a new method based on expert systems for fault diagnosis of aircraft fuel system is presented in this paper.The relevant software environment is set up by building a knowledge base and inference engine and using LabVIEW tool.Consequently the fault diagnostic system of aircraft fuel systems is successfully developed.The simulation results show that the intelligence of the expert system works perfectly and faults in fuel systems are diagnosed exactly and fast.Furthermore,effective reconfiguration concepts can be provided by the expert system and is entirely practicable for aircraft fuel system fault diagnosis.
