CA 2306156
A processor system (100) and method are provided for providing motor excitation frequency control in a vehicle propelled by AC electric traction motors (M1-M4). The processor system and method allow for computing an excitation frequency signal based on a sum of i) a signal indicative of a weighted average of an estimated rotor speed signal and a measured vehicle speed signal and ii) a compensated slip command signal.
Système processeur (100) et méthode de commande de la fréquence d'excitation d'un moteur dans un véhicule propulsé par des moteurs de traction électrique c.a. (M1-M4). Le système processeur et la méthode permettent de calculer un signal de fréquence d'excitation d'après la somme i) d'un signal indicatif d'une moyenne pondérée d'un signal de vitesse de rotor estimée et d'un signal de vitesse de véhicule mesurée et ii) d'un signal de commande de vitesse de glissement compensée.
