Abstract
P rocédé et dispositif de mesure de la position angulaire mécanique d’un rotor L’invention concerne un procédé et un dispositif de mesure de la position angulaire mécanique d’un rotor comportant, pendant une phase de calibration puis une phase de calage: - l’acquisition de Ns signaux de mesure, en des endroits de mesure décalés d’un angle mécanique correspondant, modulo 2Pi/Nc radians d’angle, à Pi/(2 x Nc) radians pour Ns=2 et 2Pi/3Nc radians pour Ns=3 ; - le calcul informatique d’une valeur instantanée de la position angulaire électrique en prenant en compte l’arc-tangente du rapport des valeurs des deux signaux de mesure pour l’instant considéré, ou l’arc-tangente du rapport des valeurs des deux transformées obtenues par une transformée de Clarke, appliquée à trois signaux de mesure ; - la détermination de signatures électriques de calibration (SIGcb) et de calage (Sigi) ; - la détermination d’une valeur de décalage angulaire de mesure par une opération de recalage des signatures. Figure pour l’abrégé : Fig. 11.
