n the last 10-15 years, control of paper variation in the cross I machine direction has become a necessary requirement to meet increasing quality demands. Traditional approaches to the control of weight, moisture and caliper have realized good reductions in paper profile variability using relatively simple control technology. Recent advances in computer(More)
Abstruct-In this paper an improved estimation algorithm for use in processing data generated on-line by a scanning sensor is described. The algorithm is to be used as part of a pa&r machine control system to maintain the moisture content of the sheet at a target v h e . The algorithm makes use of a previously published model to rapidly estimate, in the(More)
