Abstract
A control system configured to control an electric motor of an electric vehicle (EV) includes a current sensor offset detector that determines an offset of one or more current sensors; a gain compensator that determines a second order harmonic component in d- and q-axis currents due to gain errors in one or more sensors; and a controller that generates a control signal that compensates for the offset or gain error mismatch of the current sensor(s).
