Ensemble of One-Class Classifiers for Detecting Faults in Induction Motors

This paper studies the use of an ensemble of one-class classifiers for broken rotor bars detection in an induction motors. To achieve this goal, the current signal of induction motor is considered into account for the sake of detection. The fault detector is a multiple classifiers system (MCS), which combines various one-class classifiers to enhance the accuracy of the monitoring system compared to individual one-class classifiers. One-class classifiers are combined in different manners to form the ensembles. These include random subspace, bagging and boosting strategies. These ensemble-based schemes are constructed in homogeneous and heterogeneous configuration and compared together for the purpose of fault detection in induction motors.
