Abstract[English]
System and methods for detecting a phase voltage of a poly-phase motor are described. The method includes receiving, by a controller, a collection of readings from an auxiliary coil installed in the motor; converting, by the controller, the collection of readings to a plurality of principal components, wherein the principal components are based on eigen vectors and eigen values generated based on the spectrum of readings; and inputting the plurality of primary components into a trained machine learning model to obtain a predicted phase voltage of the motor.[French]
L'invention concerne un système et des procédés de détection d'une tension de phase d'un moteur polyphasé. Le procédé consiste à recevoir, par un dispositif de commande, un recueil de relevés d'une bobine auxiliaire installée dans le moteur ; convertir, au moyen du dispositif de commande, le recueil de relevés en une pluralité de composantes principales, les composantes principales étant basées sur des vecteurs propres et des valeurs propres générés sur la base du spectre de relevés ; et entrer la pluralité de composantes primaires dans un modèle d'apprentissage automatique entraîné pour obtenir une tension de phase prédite du moteur.
