Method of controlling a permanent-magnet synchronous machine, comprising: - a measurement (110) of the current (I1, I2, I3) delivered on the three phases of the machine, - a transposition (120) of the three currents measured into a direct component (Id) and a quadratic component (Iq) of current on the basis of a transform of the three-phase system, - the reception (130) of a quadratic setpoint (Iq _req) of current and of a direct setpoint (Id_req) of current, - a calculation (160) of the direct and quadratic components of the nonsaturated control voltage (Vd_nonsat, Vq nonsat) on the basis of the components and of the direct and quadratic setpoints of current (Id, Iq, Id_req, Iq_req)> - a calculation (170) of the direct and quadratic components of the saturated control voltage (Vd_sat, Vq_sat) on the basis of the component and of the quadratic setpoint of current (Iq, Iq_req), - a control (190, 200) of the synchronous machine on the basis of the nonsaturated controls if the direct component of the current (Id) is positive, or on the basis of the saturated controls if the direct component of the current (Id) is negative. |
