Title (EN) MOTOR DRIVE SYSTEM AND METHOD
(FR) SYSTÈME ET PROCÉDÉ D'ENTRAÎNEMENT DE MOTEUR
Abstract:
(EN) A motor drive and method to control a motor in a fluid system. The method may comprise determining a pressure; determining a proportional error as a limited difference between the pressure and a pressure setpoint; determining an integral step as a limited proportional error; determining an integral error as a limited sum of the integral step and a preceding unbound integral error; determining an error as the product of the integral error, the proportional error, and a gain factor; and generating a control signal to cause the inverter to output a motor voltage to drive the motor and maintain the pressure about the pressure setpoint.
(FR) L'invention concerne un système et un procédé d'entraînement de moteur permettant de commander un moteur dans un système fluidique. Le procédé peut comprendre la détermination d'une pression; la détermination d'une erreur proportionnelle comme une différence limitée entre la pression et un point de consigne de pression; la détermination d'une étape intégrée comme une erreur proportionnelle limitée; la détermination d'une erreur intégrée comme une somme limitée de l'étape intégrée et d'une erreur intégrée non liée précédente; la détermination d'une erreur comme le produit de l'erreur intégrée, de l'erreur proportionnelle et d'un facteur de gain; et la génération d'un signal de commande pour amener l'onduleur à distribuer en sortie une tension de moteur pour entraîner le moteur et maintenir la pression autour du point de consigne de pression.
