For samples less vibration fault OLTC single feature extraction method, we propose a feature fusion and machinery fault diagnosis method OLTC IPSO-KNN combination.
In view of the small sample of OLTC vibration fault and the single method of feature extraction, a combination of multi-feature fusion and IPSO-KNN combined OLTC mechanical fault diagnosis method is proposed.
In view of the small number of samples and single feature extraction method of OLTC vibration fault, this paper proposes a method of OLTC mechanical fault diagnosis which combines multi feature fusion and ipso-knn.
