FAULT DETECTION BASED ON GAUSSIAN PROCESS MODELS - An Application to the Rolling Mill

Abstract

In this paper a fault detection approach based on Gaussian process model is proposed. The problem we raise is how to deal with insufficiently validated models during surveillance of nonlinear plants given the fact that tentative model-plant miss-match in such a case can cause false alarms. To avoid the risk, a novel model validity index is suggested in order to quantify the level of confidence associated to the detection results. This index is based on estimated ‘distance’ between the current process data from data employed in the learning set. The effectiveness of the test is demonstrated on data records obtained from operating cold rolling mill.
