Abstract
A complete fault detection and isolation system is designed for a gas-liqui d separation unit. It involves the determination and identification of grey box models, the design of a model-based residual generator, and finally th e evaluation of the residuals via a set of statistical tests. The latter ar e cumulative sum (CUSUM) tests which are combined in such a way that both f ault detection and fault isolation can be achieved. The performance of the resulting diagnosis system, such as missed alarm rate: wrong isolation rate and mean detection delay, are studied via simulations. (C) 2000 Elsevier S cience Ltd.
