Abstract
This paper presents the Warkaus Mill computer system and is focused particularly on the paper web moisture profile control developed in our company. The aim is to make use of the possibilities given by the second and the third presses with controlled crown rolls. Special attention is directed to profile measurement data analysis techniques and an on-line continuous statistical variation partitioning method is developed . The information is then used for operator guidance control, based on a derived control law . The profile control is not yet integrated in the system, but the control parameters are being established.
