摘要

In this paper is proposed an on-line approach to fault detection and diagnosis (FDI) in dynamical systems, that combines Artificial Neural Networks (ANNs) as observers and pattern classifiers, and statistical analysis of residuals. The robust FDI problem is also addressed. The approach is applied to a real laboratory set-up tank system under closed-loop control. Component and instrument abrupt faults are considered.
