軟測量技術(shù)及其應(yīng)用 Soft Sensing Technology and Its Applicatio

摘要:軟測量技術(shù)是當(dāng)前過程控制中研究熱點之一。在介紹軟測量技術(shù)基礎(chǔ)上，對目前主要軟測量建模的方法:機理建模、回歸分析、狀態(tài)估計、模式識別、人工神經(jīng)網(wǎng)絡(luò)、模糊數(shù)學(xué)、基于支持向量機(SVM)和核函數(shù)的方法、過程層析成像、相關(guān)分析和現(xiàn)代非線性系統(tǒng)信息處理技術(shù)等十種方法進行介紹，并對軟測量建模方法進行了展望。最后列舉了工業(yè)應(yīng)用實例。

Abstract; At present, soft sensing technology is one of the topics of general interest in study on current process control. On the basis of introductiontos oftse nsingte chnology,te no fth em ajorm odelingm ethodso fso ftse nsing,i. e. m echanismm odeling,re gressiona nalysis,st atee stimation,pattern recognition, artificial neural network, fuzzy mathematics, and SVM- or kernel-function-based method, process tomography,correlative analysis and non-linear system information processing technology are introduced, and the modeling method of soft sensing is prospected.
Finally the practical examples of industrial applications are illustrated.
