DETECTION, DIAGNOSIS AND FAULT CORRECTION: A CONSISTENT PROPOSITION OF DEFINITIONS AND TERMINOLOGY

Abstract

ABSTRACT The increasing complexity of industrial systems and the consequent growth in instrumentation and process automation have given FDDC - Fault Detection, Diagnosis and Correction - systems an increasingly important role. This paper reflects on research into fault detection, diagnosis and correction through a critical analysis of the definitions and terminology used. The terminology and definitions that seem most appropriate for the research field, for its activities and for its object of study are proposed to conciliate the clash of visions of various authors, since this was not done yet by any work of literature. Furthermore, the most commonly studied industrial systems are highlighted as well as the most commonly used techniques in recent works with applications in these industrial problems. Keywords: Fault detection, diagnosis and correction; industrial processes; definitions; terminology.
