Method of controlling an asynchronous electric machine of a power train of an automotive vehicle, comprising the following steps: a torque request ( Ce #)and the speed of rotation of the asynchronous electric machine are determined, a request for rotor flux (φ r #) as a function of a mapping dependent on the torque request and on the speed of rotation (Ω) is determined, requests for direct and quadrature components of the stator current (I ds, I qs) as a function of the request for rotor flux and the torque request are determined, the angle that the rotating field forms with respect to a fixed frame with respect to the stator (θ s) as a function of the request for rotor torque, of the request for quadrature component of the stator current, and of the rate of the rotor, of the number of pairs of poles of the electric machine and of the speed of rotation is determined, the direct and quadrature components of the stator voltage (V ds, V qs) are determined as a function of combinations of the request for direct and quadrature components of the stator current, the values of voltages of the stator in the three-phase frame are determined as a function of the direct and quadrature components of the stator voltages in the Park frame and of the angle that the rotating field (θ r) forms with respect to the fixed frame with respect to the stator. |
