Monitoring the Stator Current in Induction Machines for Possible Fault Detection: A Fuzzy/Bayesian Approach for the Problem of Time Series Multiple Change Point Detection

Abstract

ABSTRACT. This paper addresses the problem of fault detection in stator winding of induction machine by a multiple change points detection approach in time series. To handle this problem a new fuzzy/Bayesian approach is proposed which differs from previous approaches since it does not require prior information as: the number of change points or the characterization of the data probabilistic distribution. The approach has been applied in the monitoring the current of the stator winding induction machine. The good results obtained by proposed methodology illustrate its efficiency.
