1. A method of controlling a vehicle dc bus voltage, the method comprising:

  • generating a first parameter, by a controller, the first parameter being based on a reference dc bus voltage squared;

    generating a second parameter, by the controller, the second parameter being based on a detected dc bus voltage squared; and

    controlling, by the controller, the vehicle dc bus voltage, the controlling including,determining a square error difference between the first parameter and the second parameter,determining a sign of the square error difference and whether to adjust the sign of the square error difference based on a mode of a generator associated with the vehicle, the mode being one of a motoring mode operation and a generating mode, andcontrolling the vehicle dc bus voltage based on the square error difference and the sign of the square error difference.
