| 摘 要： | 通过电解温度,工作电压,出铝量,添加氟化物次数等历史数据,利用矩阵主轴旋转法建立铝电解温度预测模型,预测未来的电解温度。此方法将一个多元预测问题简化为若干一元预测问题,预测值与实际值的拟合度很高。选取两个电解槽进行实验,50多天的预测值与实际值的标准差分别为1.2634,0.9358。

| Abstract: | The main purpose of the paper is to predict the future temperature of aluminium production cells with forecast model built based on rotations of principal axes of orthogonal matrice by use of historical data of temperature,working voltage,aluminium tapping amount and fluoride addition times.The method simplified a multiple regression problem into several simple regression problems.The predicted value and the actual value were very close.Choosing two aluminium production cells for experiment for over 50 days,it showed that the standard deviation of the predicted value and the actual value were 1.2634 and 0.9358 respectively,which were close enough to be accepted. |
