ABSTRACT:
A method and system for controlling an electric machine using voltage mode control comprising: receiving a voltage command, the voltage command corresponding to a voltage control command for a position control loop, the position control loop configured to control a position of the electric machine; receiving a motor velocity signal; and determining a q-axis current. The method also includes computing a d-axis current to supplement the torque if a magnitude of a voltage supply for exciting the electric machine is not sufficient to provide a torque corresponding to the q-axis current, otherwise establishing the d-axis current at about zero; and generating command voltages for controlling the electric machine corresponding to the q-axis current and the d-axis current.
