Abstract: A controller to provide base level fiber orientation control of a paper web. The controller achieves one or more indices that are derived from the online measurements of a fiber orientation sensor of the fiber ratio and the fiber angle. The indices are used for control of the sheet forming processes. The controller may be implemented by a single or multi stage fuzzy controller or the combination of fuzzy controllers with non-fuzzy logic controllers.
