A method and apparatus are set forth for controlling and actuator in a moving web manufacturing process. The method includes: (1) measuring a plurality of actuator profiles and in response generating nominal response models thereof; (2) generating a multivariable profile prediction based on the nominal response models; (3) generating a multivariable control target based at least one of the actuator profile; and (4) adjusting control of the actuator by minimizing error between the multivariable control target and the multivariable profile prediction.

Method and apparatus for reel building and roll runnability in moving web manufacturing

The invention relates to a method in the manufacture of a fiber-based web-like product for optimizing the operation of the process being used, in which method quality factors are defined for the product being manufactured control variables, which affect the state of the process, or quality factors of the finished product, are defined for at least part of the process. In addition, an operating model is created, which is used to depict the effect of each control variable on the quality factors, and a user interface is created, through which varying values for the control variables can be input to the operating model and the values of the quality factors can be depicted simultaneously, in such a way that the values of the control variables and the values of the quality factors can be viewed simultaneously.
