A system for controlling an automotive vehicle three-phase electric machine supplied via chopped voltages, including: a mechanism determining settings of current of phases of the electric machine as a function of a torque request from a driver; a regulating mechanism to determine voltages of each phase as a function of corresponding settings of current; a mechanism correcting torque oscillations, which can determine powers of each phase, to determine whether speed of rotation of the magnetic field exceeds a threshold value, to carry out a bandpass filtering of the powers, and to determine attenuation currents relating to each phase as a function of the post-filtering powers; subtractors configured to subtract the attenuation currents relating to each phase from the settings of current of the corresponding phases, destined for the regulating mechanism.
