Abstract:
(EN) A motor control device 110 is provided with: a difference calculation unit 113 which calculates a difference between a current number of revolutions and a target number of revolutions of a motor; a coefficient correction unit 117 which multiplies each of initially set proportional coefficient and integral coefficient by a correction coefficient, and outputs corrected proportional coefficient and integral coefficient; an output voltage determination unit 114 which calculates at least one of a proportional term obtained by multiplying the difference by the corrected proportional coefficient and an integral term obtained by multiplying the difference by the corrected integral coefficient, and which determines one of the proportional term and the integral term, or a sum of the two terms, as a control value for the output voltage; and a signal generation unit 115 which generates a control signal on the basis of the control value. The correction coefficient has the value of the ratio of a reference voltage to a current input voltage of the inverter. The reference voltage is an input voltage of the inverter 102 that was in use or assumed at the time of determining the initially set proportional coefficient and integral coefficient.
(FR) La présente invention concerne un dispositif de commande de moteur (110) qui est pourvu : d'une unité de calcul de différence (113) qui calcule une différence entre un nombre actuel de rotations et un nombre cible de rotations d'un moteur ; d'une unité de correction de coefficient (117) qui multiplie un coefficient proportionnel et un coefficient intégral définis initialement par un coefficient de correction, et délivre un coefficient proportionnel et un coefficient intégral corrigés ; d'une unité de détermination de tension de sortie (114) qui calcule un terme proportionnel obtenu en multipliant la différence par le coefficient proportionnel corrigé et/ou un terme intégral obtenu en multipliant la différence par le coefficient intégral corrigé, et qui établit le terme proportionnel, le terme intégral ou une somme des deux termes, en tant que valeur de commande de la tension de sortie ; et d'une unité de génération de signal qui génère un signal de commande basé sur la valeur de commande. Le coefficient de correction a la valeur du rapport d'une tension de référence à une tension d'entrée actuelle de l'onduleur. La tension de référence est une tension d'entrée de l'onduleur (102) qui était utilisée ou supposée au moment de la détermination du coefficient proportionnel et du coefficient intégral définis initialement.
