Fuzzy cognitive logic models for diagnostics and predictive evaluation of the health of electromechanical systems

The paper discusses an approach to the maintenance diagnostics and predictive evaluation of the operational health of electromechanical systems (EMS). It presents a mathematical model of an EMS, which is intended for problems of diagnosing an individual EMS and an EMS operation mode group, offers information on the EMS vector spaces, and describes the general methodology for vector space testing. To solve problems of the maintenance diagnostics and predictive evaluation of EMS health, it is proposed to use hybrid models based on a combination of the fuzzy cognitive approach and the fuzzy logic one.
