    摘要: A processor system and method are provided for providing motor excitation frequency control in a vehicle propelled by AC electric traction motors. 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. Effective wheel slip control is thus provided without requiring sensors for measuring rotational speed of the traction motors.
