摘要: A caliper profile control system for a paper machine provides reduced start up times after sheet breaks to bring the across within desired limits. The method comprises steps of scanning at predetermined intervals width monitor thickness error from limits and change in between intervals, each plurality zones sheet. signal is determined based on using an exponential function magnitude maximize reduce integral action when large. used zone increased as decreases until are met.
