CD response modelling for control of a paper machine

This article considers wet end modelling of a Fourdrinier table. Cross direction (CD) response to an actuator adjustment is the principal requirement for a good CD basis weight profile control. The physical basis of the model is a surface wave generated by the deflected slice on the surface of the slurry. The wave model combined with the drainage from the wire side establishes the mat formation process. This approach to modelling eliminates the need for estimating a large matrix when a purely time series parametrization of the CD response is considered
