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)
The paper addresses two interrelated problems in cross-directional (CD) control of papermaking processes. The rst problem is explaining paper property streaks observed in many CD control installations. The streaks usually correspond to the high-resolution error pro le harmonics with wavelength close to twice the actuator spacing. Typically, the streaks of(More)
