1. A method of controlling a motor in a motor control system, the method comprising:

  • receiving a supply voltage signal and a motor torque command, the motor torque command specifying a desired motor torque to be generated by an electric motor;

    determining a control voltage budget value based on an operating region of the motor, the control voltage budget value being a retained portion of an available supply voltage;

    adjusting the supply voltage signal based on the control voltage budget value by subtracting the control voltage budget value from the supply voltage signal;

    determining a reference current command based on the adjusted supply voltage signal; and

    applying the reference current command to a current regulator, the current regulator configured to generate a motor voltage command to the motor based on the reference current command, the motor voltage command configured to cause the motor to generate the desired motor torque.
