    • The invention relates to a method for controlling a synchronous electric machine with a wound rotor for an electric or hybrid motor vehicle, comprising steps involving: measurement of the rotor and stator phase currents and voltages in the three-phase reference frame; and determination of the rotor and stator phase currents and voltages in the two-phase reference frame according to the measurements of current and voltage in the three-phase reference frame. The method comprises steps during which the position and the speed of the rotor is determined in relation to the stator by an observer according to the stator and rotor voltages and currents expressed in the two-phase reference frame, and the observer is regulated by a discrete extended Kalman algorithm.
