Research of technical state of electric motors based on petri nets

In this work, the possibility of using Petri nets when monitoring the technical condition and diagnostics of electric motors is considered. Based on the use of fuzzy temporary Petri nets, a mathematical model of the process diagnostic has been developed. The control of the technical conditions of the electric motor in the model is done based on the cluster analysis. The description of the diagnostic process is carried out using a set of events, states, transitions, input and output functions, markers, parameters of time delays. Figs.: 3. Tabl.: 1.
