Fault Diagnosis of Airplane ADIRS Based on Rough Sets-FPN
Rui Zhang · Measurement & Control Technology · 2012
As the complexity in internal structure and control mechanism of ADIRS(air data inertial reference system),the fault information often follows redundant and uncertain information.It is helpful in overcoming the limitation of complex structure of Petri net which comes from the problem by combining with rough sets and fuzzy Petri nets properly.According to the failure of airspeed disagree in ADIRS,the fault samples were reduced using rough sets theory to delete redundant information firstly,then structure corresponding fuzzy Petri nets and come to the diagnosis finally.The example analysis shows that the algorithm is feasible and shortens the diagnostic time.
