Title (EN) CONTROLLER AND METHOD FOR TRANSITIONING BETWEEN CONTROL ANGLES
(FR) DISPOSITIF DE COMMANDE ET PROCÉDÉ PERMETTANT D'ASSURER LA TRANSITION ENTRE DES ANGLES DE COMMANDE
Abstract: front page image
(EN)A system includes a pulse-width modulation (PWM) module, a subtraction module, an error reducing module, and a summing module. The PWM module controls switching of an inverter that powers a motor. The PWM module controls the switching based on a first angle in a first mode and a second angle in a second mode. The subtraction module determines a difference between the first and second angles. The error reducing module (i) stores the difference when a transition from the first mode to the second mode is commanded and (ii) decreases a magnitude of the stored difference to zero. The summing module calculates a sum of the stored difference and the second angle. The PWM module controls the switching based on the sum in the second mode.
(FR)L'invention concerne un système comprenant un module de modulation d'impulsion en durée (MID), un module de soustraction, un module de réduction d'erreur et un module de sommation. Le module de MID commande la commutation d'un onduleur qui alimente un moteur. Le module de MID commande la commutation sur la base d'un premier angle dans un premier mode et d'un second angle dans un second mode. Le module de soustraction détermine une différence entre le premier angle et le second angle. Le module de réduction d'erreur (i) stocke la différence quand une transition du premier mode vers le second mode est commandée et (ii) réduit une amplitude de la différence stockée à zéro. Le module de sommation calcule la somme entre la différence stockée et le second angle. Le module de MID commande la commutation sur la base de la somme dans le second mode.
