Multi-parameter fast fault diagnosis model of aeroengine
航空发动机的多参数快速故障诊断模型*

For the sake of improving efficiency of diagnosis and lowering the dependency of manual labor,this paper proposed a fast fault diagnosis model of aeroengine.The model combined characteristics of rough sets and grey theory.Redundant information was eliminated from feature information by rough sets,and then the reduction information was quickly and accurately predicted by multi-parameter grey model.The simulation results show preliminarily that the model saves the computing time greatly and can effectively me...
