| Abstract: | The paper introduces the principle and algorithm of SVM,analyzes the delamination and its application to the fault diagnosis,and constructs the fault model of diesel engine with the help of above-mentioned theories.The simulation results indicate that SVM could fulfil the classification of fault diagnosis of diesel engine in a condition of small samples,which is supposed to have a comprehensive prospect in practice. |
