3 APPROACHES TO FAULT-DETECTION AND DIAGNOSIS OF TECHNICAL PLANTS

The problem of fault detection and diagnosis of the state (good, opera ble, etc.) of technical plants is considered. The existing algorithms are shown to realize mostly one of two approaches, cabled here classif ication and indicator approaches. Using the principle of matching vp t wo systems by their input-output: sets, which is formulated in the pre sent paper, a third approach based on solving the so-called abstract p roblem of fault detection and diagnosis is proposed. It is expected th at the development of this approach and the realization of the corresp onding algorithms will enable one not only to generalize and represent in a new way the existing methods for fault detection and diagnosis, but also do reveal their additional capabilities.
