| Abstract: | A new online correction method for soft sensor model is presented.The correlation between variables is studied in the new soft sensor model correction method.In the method,the value of coefficient is determined by correlation coefficient and property of the variables,and the real-time performance and flexibility of the soft sensor model are improved.This method is successfully applied in the measurement of resistance value in the industrial process of calcium carbide manufacture. |
| Keywords: | soft sensor online correction correction coefficient correlation coefficient |
