Title
(EN) ESTIMATOR INITIALIZATION CIRCUIT AND METHOD FOR A SENSORLESS SWITCHED RELUCTANCE MACHINE SYSTEM
(FR) CIRCUIT D'INITIALISATION D'ESTIMATEUR ET PROCEDE POUR SYSTEME DE MACHINE SRM SANS CAPTEUR
Abstract
(EN)
An estimator initialization circuit for a sensorless switched reluctance machine system pulses phase windings of the machine a certain number of times and derives initial values for an estimator of the system.
(FR)
L'invention concerne un circuit d'initialisation d'estimateur pour système de machine SRM sans capteur qui active les enroulements de phases de la machine un certain nombre de fois et calcule des valeurs initiales pour un estimateur du système.
