| 摘 要： | 针对线性PLSR在多传感信息回归建模中存在不足,提出了一种基于INLR-PPLS的非线性多传感耦合信息建模新方法。首先用线性PLSR对传感信息进行预处理，达到降维的效果，然后基于INLR外模型非线性样本矩阵变换、基于PPLS内模型非线性映射、多传感非线性回归模型反求，实现对非线性多传感耦合信息的建模。应用于液态乙醇浓度测控系统的实验表明，该方法较线性PLSR预测准确度提高21%。

| Abstract: | In allusion to deficiency of linear PLSR for multi-sensor information modelling, a novel modelling approach of nonlinear multi-sensor coupling information based on INLR-PPLS is put forward. The multi-sensor information is preprocessed first by means of linear PLSR to descend dimensions, then integrated INLR to construct outer model through nonlinear sample matrix transform and PPLS to form inter model by nonlinear mapping. Finally, the reverse regression model is accomplished. From the experiment of alcohol concentration measurement, the results indicate that the prediction accuracy of proposed approach is raised 21% at average, comparing to the linear PLSR in the similar industrial circumstances. |
