Performance evaluation of the QCS at Paper Machine 6, Arctic Paper Håfreström AB
2005 (English)Independent thesis Basic level (professional degree)Student thesis
Abstract [en]

A new Quality Control System has been installed at paper machine 6 (PM6), Arctic Paper Håfreström AB. At the same time, new scanners and some additional control equipment was also installed. This paper highlights the difficulties involved when comparing statistics from the old system with statistics from the new one. Several factors have been recognized as especially infuential. An attempt has also been made to show approximately how different factors affects the statistics. A number of mathematical tools like frequency analysis, principal component analysis and autocorrelation have been shown valuable in analyzing papermachine control systems. Several examples are shown where these tools have been put to use in the case of PM6 Arctic Paper Håfreström.
