Ld. Desborough et Tj. Harris, CONTROL PERFORMANCE ASSESSMENT - A METHOD TO DIAGNOSE LOOP PROBLEMS IS DISCUSSED, Pulp & paper Canada, 95(11), 1994, pp. 35-37
Means for assessing the performance of feedback-only and combined feed
forward/feedback control using routine operating data are described. A
n analysis of variance is developed which decomposes the process varia
nce by disturbance and by controller, allowing tile existing controlle
r's performance to be compared with a benchmark of minimum variance co
ntrol. Industrial data are used ro demonstrate the utility of the meth
ods described.
