Embodiment Construction
[0057] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.
[0058] The embodiment of the present invention provides a fault monitoring and diagnosis method based on multi-feature fusion and width learning.
[0059] In this embodiment, a simulation experiment is designed based on the public model TE (Tennessee Eastman) chemical process to verify the effectiveness of the fault diagnosis method based on multi-feature fusion. The data used come from TE simulation experiments, and there are 52 observation variables in each sample in the TE set. According to Table 1, 52 variables are classified, and the original variables (such as Table 1) that need feature extraction are distinguished. Based on the mechanism analysis, the variables in the historical process signal are divided into co...
