| Abstract: | Aiming at the problems of high temperature,strong corrosion and difficulty of direct measurement of the temperature,a soft measurement model of electrolyte temperature is proposed based on least square support vector machine(LS-SVM).The model is based on the analysis of aluminum electrolytic production procedure and influencing factors of electrolyte temperature.A simulation carried out according to the actual production figures and the results show that the soft-sensing of electrolyte temperature based on LS-SVM model is with high precision and good generalization performance.The results indicate that LS-SVM is an effective method in soft-sensing of aluminum electrolyte’s temperature. |
