| titleOfInvention | A soft measurement method for dioxin emission concentration in urban solid waste incineration process |
| abstract | The invention discloses a DXN emission concentration soft measurement method based on multi-source latent feature selective integration (SEN) modeling. First, the MSWI process data is divided into subsystems from different sources according to the industrial process, and the potential features are extracted by principal component analysis (PCA), and the multi-source potential features are initially selected according to the threshold of the principal component contribution rate preset by experience; then , using mutual information (MI) to measure the correlation between the potential features of the primary selection and DXN, and adaptively determine the upper and lower bounds and thresholds of the potential feature re-selection; finally, based on the re-selection potential features, adopt a hyperparameter adaptive selection mechanism. The least squares-support vector machine (LS-SVM) algorithm is used to establish DXN emission concentration sub-models for different subsystems, and a strategy based on branch and bound (BB) and prediction error information entropy weighting algorithm is used to optimize the selection of sub-models and calculation weights coefficient to construct the SEN soft-sensor model of DXN emission concentration. |
