    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.

    摘要: The system and method maximize available rail adhesion between the rails of a track and the wheels of a rail vehicle so that the vehicle is better able to accelerate up to operating speed and to decelerate to a stop condition under poor rail conditions. The system implements a control logic function which relies on a measured variable that is different than the controlled error signal utilized to affect control of the vehicle. The control system is enabled based on creep speed while the parameter used to effect control is wheel acceleration.
