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.
