Research on Erroneous Data Identification of Aero-engine Based on Grey System Theory
In order to identify erroneous data from numerous test data of aero-engine,grey system theory is introduced and grey identification method is developed to identify erroneous data.Test data of an aero-engine is judged with grey identification method,and the erroneous data is identified accurately by computing upper and lower boundary function to form grey range.The grey identification method is validated and the analysis shows that the grey identification method is reliable that can identify erroneous data with high precision.Grey system theory has a better application prospect in identi-fying erroneous data from complicated test data of an aero-engine.
