Застосування адаптивних порогів у системах виявлення і локалізації несправностей

Abstract

The aim of the presented work is to study the problem of the difference signal former stability as a source of the error signal in the concept of model-based methods for detecting, localizing and identifying faults. Since the basis of the methods used is a mathematical model of the controlled object, the problem of resistance to composite modeling errors is the actual modern problem. It has been determined that the use of adaptive thresholds is characterized as a passive method of ensuring resistance, which does not require additional efforts to form a stable difference signal. It is noted that a combination of active and passive methods for ensuring the resistance of the difference signal to the indicated uncertainties can be an effective tool for achieving the stability of systems for identifying and localizing faults in practical situations.
