CAUSAL MODEL BASED FAULT DIAGNOSIS APPLIED ON A PAPER MACHINE SIMULATOR

The aim of the work presented in this paper is to evaluate the ability of the causal digraph method to detect and isolate faults on a simulated paper machine process. A causal digraph model for the short circulation process of the paper machine was constructed, identified and used to detect and isolate artificial faults in the simulation environment. The fault of headbox slice opening was studied and diagnosed.
