| Abstract: | This paper provides a SVM fault diagnosis technique based on Gauss kernel, and the grid method is used to get optimization SVM parameters in order to gain the best classified precision. Through researching on fault diagnosis of one AE3007 engine on ERJI45 aircraft, it indicates that the SVM based on Gauss kernel model has good applicability and creditability and can provide effective reference for aeroengine fault diagnosis. |
