摘要
介绍了软测量技术常用的建模方法，分析了优缺在。采用静态线性软测量模型的回归分析法，实现对纸张水分的软测量。模型参数的辨识采用最小二乘法及对病态方程仍稳定的Ｈｏｕｓｅｈｏｌｄｅｒ变换法。然后给出了软测量模型的在线校正方法。
The commonly used modeling methods in software measurement are introduced. The merits and demerits are analzed. The soft measurement of moisture of paper is implemented by using regression analysis on static linear software measurement model .The recog nition on model parameters is accomplished by the least square method and the householder transformation which is still stable on equations in abnormal sate. The correction method for soft measurerment model is given finally.
