An electric drive system includes a fuel-driven prime mover for driving an electrical power alternator controlled at least in part by an excitation voltage is disclosed. The electrical power alternator makes electrical power available on a DC link having a voltage characteristic and a current characteristic. A method for managing the response of the alternator includes determining a voltage of the DC link and a torque command by an operator. The torque command is used to derive a mechanical power that is being commanded. A desired voltage of the DC link is determined based on the derived mechanical power, and an excitation voltage command signal is provided based on the desired voltage of the DC link by use of a closed loop controller. An actual excitation voltage is applied to the electrical power alternator based on the excitation voltage command signal.
