System for controlling the electromagnetic torque of an electric machine in particular for motor vehicle. System for control (1) of the electromagnetic torque of a permanent-magnet three-phase electric machine (10), comprising means (2) for measuring the current, transposition means (3) able to transpose the three measured currents into a direct component (Id) and a quadratic component (Iq) of current on the basis of a transform of three-phase systems, transformation means (4) able to convert a torque setpoint (Creq em) into a setpoint (lreq) for the quadratic component (Iq) of current and a setpoint (I req) for the direct component (la) of current, means for determining the control voltages (U1, U2, U3), and control means (9) able to apply the control voltages (U1, U2, U3) determined to the electric machine ( 10). |
