Abstract
A motor control system for determining a reference d-axis current is provided, and includes a motor, a DC power source and DC input lines, and a current command controller. The DC power source generates a bridge voltage across the DC input lines. The current command controller is in communication with the motor and the DC input lines. The current command controller is configured to monitor the bridge voltage and a torque reference command. The current command controller is configured to determine a peak current based on the torque reference command. The current command controller is configured to determine a current angle based on the peak current. The current command controller is configured to determine the reference d-axis current based on the current angle.
