Patent

CA 2754665

A system and method are provided for controlling the speed of a motor driving a load that is electrically connected to a generator driven by an engine, through use of a first control feedback loop configured to control the rotor flux of the motor by controlling the field excitation of the generator, and a second control feedback loop configured to control the speed of the motor by controlling the throttle position of the engine.

La présente invention concerne un système et un procédé permettant la commande de la vitesse d'un moteur entraînant une charge qui est en liaison électrique avec un générateur entraîné par un moteur, grâce à l'utilisation d'une première boucle de rétroaction de commande configurée pour commander le flux de rotor du moteur par la commande du champ d'excitation du générateur, et une seconde boucle de rétroaction de commande configurée pour commander la vitesse du moteur par la commande de la position du papillon des gaz du moteur.
