An electric power system including a front-end converter that is supplied electric power from a high-voltage DC power source, and an associated motor control system is described. A control method includes monitoring the electric machine and determining a reference current based upon the electric power supplied from the high-voltage DC power source. A motor current is determined based upon the monitoring of the electric machine, and a feed-forward current is determined based upon the motor current and the monitoring of the electric machine. A first duty cycle is determined based upon the reference current, the motor current and the feed-forward current, and a feed-forward duty cycle is determined based upon the monitoring of the electric machine. A second duty cycle is determined based upon the feed-forward duty cycle and the first duty cycle, and the front-end converter is controlled based upon the second duty cycle.
