Abstract:
To cope with the characteristics of sample imbalance, high dimensionality and nonlinearity in chemical process fault diagnosis, an SVMSOMTE-LPP fault diagnosis method is proposed in this paper. Firstly, the SVMSOMTE algorithm is used to expand the imbalanced samples of the fault diagnosis. Then the LPP algorithm is used for dimensionality reduction of the balanced samples, which can extract the main fault-related features and retain the valuable manifold geometry structure. Finally, the Bag-Tree classifier is chosen to classify the dimensionality reduced data. To verify the proposed method, the TE process case is used, and the simulation results show that the proposed method has good fault diagnosis accuracy.
