Title (EN) CONTROL OF A PERMANENT-MAGNET ELECTRIC MACHINE
(FR) COMMANDE D'UNE MACHINE ELECTRIQUE A AIMANTS PERMANENTS.
Abstract:
(EN) The invention relates to a method of controlling a permanent-magnet synchronous machine (3) comprising a stator and a rotor. The method comprises a step of determining an estimated position ($) of the rotor, a step of determining a second direct voltage setpoint (νδ2*) which is alternately equal to a first direct voltage setpoint (νδ1*) or equal to the first direct voltage setpoint (νδ1*) plus a predetermined periodic signal (G). The step of determining an estimated position ($) of the rotor comprises a step of determining a coupling term (Δϊγ), a step of determining a speed of rotation of the rotor (Ω5) as a function of said coupling term (Δϊγ), and a step of determining the estimated position ($) of the rotor by integrating the speed of rotation of the rotor (Ω5).
(FR) L'invention concerne un procédé de commande d'une machine synchrone (3) à aimants permanents comprenant un stator et un rotor. Le procédé comprend une étape de détermination d'une position estimée ($) du rotor, une étape de détermination d'une deuxième consigne de tension directe (νδ2*) qui est alternativement égale à une première consigne de tension directe (νδ1*) ou égale à la première consigne de tension directe (νδ1*) additionnée avec un signal périodique prédéterminé (G). L'étape de détermination d'une position estimée ($) du rotor comprend une étape de détermination d'un terme de couplage (Δϊγ), une étape de détermination d'une vitesse de rotation du rotor (Ω5) en fonction dudit terme de couplage (Δϊγ), et une étape de détermination de la position estimée ($) du rotor par intégration de la vitesse de rotation du rotor (Ω5).
