Non-Linear Observer Based Method For Fault Detection and Isolation: Application to an industrial petrochemical process

摘要

This paper deals with the implementation of algorithmic fault diagnosis on an industrial petrochemical reactor. This process is cared out in a perfectly mixed reactor with a heat exchanger. The algorithm is based on a non linear geometric approach of the disturbance rejection. It allows to supervise three faults which may occur on the reactor with online temperature and pressure measurements.
