More Information
Summary:A synchronous reluctance motor control device includes current correction/calculation means (16) for generating a torque current instruction value following the load torque so that the output torque of the synchronous reluctance motor is always matched with the load torque. The control device may further include position/speed estimation/calculation means (13) for estimating position/speed based on the three-phase voltage equation in order to improve the control performance during voltage saturation. L'invention concerne un dispositif de commande d'un moteur à réluctance synchrone, comprenant un moyen de calcul/correction de courant (16) servant à produire une valeur d'instruction de courant de couple suivant le couple résistant de façon que le couple de sortie du moteur à réluctance synchrone soit toujours adapté au couple résistant. Le dispositif de commande peut également comprendre un moyen de calcul/estimation de vitesse/position (13) servant à estimer la vitesse/position sur la base d'une équation de tension triphasée, pour que le contrôle durant les phases de saturation de tension soit plus efficace.
