The invention relates to a system and method for controlling a multiphase electric motor while taking current oscillations into account. The invention relates to a system for controlling a multiphase electric motor (1) with which a motor vehicle is fitted, including a rotor (2) supplied with power by a voltage converter (4) of the rotor (2), and a stator (3) supplied with power by a multiphase voltage inverter (5), the voltage converter (4) and the multiphase voltage inverter (5) being supplied with power by a high DC-voltage bus (6), the control system receiving, as an input, a torque set value from an electric vehicle (12) computer. The control system includes a system (14) for dynamically controlling the torque set value, which is suitable for determining a dynamic torque ripple correction, and a means (9b) for determining set values for the supply of power to the electric motor according to the torque set value and the dynamic torque ripple correction. |
