Abstract
A method for controlling an electric motor includes the step of determining multi-phase voltage demand values. The method also includes the steps of determining a star voltage (vstar) of the electric motor and determining multi-phase voltage output command values as a function of the star voltage (vstar) and the multi-phase voltage demand values. The method further includes the step of supplying multi-phase voltage to the electric motor in accordance with the multi-phase voltage output command values energize the electric motor.
