Abstract

Jämsä-Jounela, Sirkka-Liisa; Vapaavuori, E.; Salmi, T.; Grönbärj, M.; Vermasvuori, M. Fault diagnosis system for the Outokumpu flash smelting process 1) Laboratory of Process Control and Automation, Aalto UniversityAbstract: Fault diagnosis systems have attracted growing interest in a number of engineering fields. The number of applications has increased and successful results have been widely reported. This paper presents and outlines a fault diagnosis system for flash smelting. The system monitors the states of the process by means of Kohonen Self-Organising Maps and performs the fault diagnosis of the process equipment by analysing the operation of the process equipment. Finally the results of the off-line testing of the system are reported and discussed.

Monitoring of an Industrial Dearomatisation Process

“…The training and analysis of the SOMs were performed with the fault diagnosis system developed by Jämsä-Jounela et al (2001). The PCA preprocessing and construction of the PLS models were made with the Matlab TM PLS_Toolbox.…”
