Abstract

Procédé (40) de commande de la régulation de la pression de suralimentation d’une turbine à géométrie variable d’un turbocompresseur d’un moteur de véhicule automobile comprenant un moteur électrique configuré pour commander l’ouverture et la fermeture des ailettes de ladite turbine, dans lequel on calcule une erreur (e(t)) en fonction d’une consigne de position angulaire du moteur électrique et d’une valeur mesurée de la position angulaire des ailettes de la turbine ; on calcule une surface de glissement (S) de convergence de la position angulaire des ailettes en fonction de ladite erreur (e(t)) et d’un paramètre de temps de convergence (τ) ; on calcule une tension discontinue (Udisc) en fonction de la valeur de la position angulaire du moteur électrique, de la valeur de la position angulaire des ailettes de la turbine, et d’un paramètre ; on calcule d’une tension équivalente (Ueq) en fonction de paramètres physiques du moteur, de la vitesse et des accélérations angulaires du moteur électrique et des ailettes de la turbine ; et on calcule une consigne de tension (U) à transmettre au moteur électrique en fonction des tensions discontinue (Udisc) et équivalente (Ueq). Figure pour l’abrégé : Fig 3Method (40) for controlling the regulation of the boost pressure of a variable geometry turbine of a turbocharger of a motor vehicle engine comprising an electric motor configured to control the opening and closing of the fins of said turbine , in which an error (e (t)) is calculated as a function of an angular position setpoint of the electric motor and of a measured value of the angular position of the blades of the turbine; a sliding surface (S) of convergence of the angular position of the fins is calculated as a function of said error (e (t)) and of a convergence time parameter (τ); a discontinuous voltage (Udisc) is calculated as a function of the value of the angular position of the electric motor, of the value of the angular position of the blades of the turbine, and of a parameter; an equivalent voltage (Ueq) is calculated as a function of physical parameters of the motor, the speed and angular accelerations of the electric motor and of the blades of the turbine; and a voltage setpoint (U) to be transmitted to the electric motor is calculated as a function of the discontinuous (Udisc) and equivalent (Ueq) voltages.
