Employing a fuzzy logic based method to the fault diagnosis of analog parts of electronic embedded systems

摘要

The article presents the new approach to employing the fuzzy logic to faults detection and localisation in analog parts ofelectronic mixed-signal embedded systems. Elaborated diagnostic method requires very few external components and it utilizes resources of a microcontroller that control embedded systems. The paper introduces additionally the way of creating the faults dictionary, characterises main parameters of fuzzy faults detection and localisation models and describes the manner of operation on the fuzzy soft decision processor.
