<p>Method for estimating the electrical angle of an asynchronous electric machine for a motor vehicle, comprising the following steps: the components of the supply currents and voltages of the rotor and of the stator of the electric machine are determined in a Clarke two-phase reference frame as a function of the components of the rotor and stator supply currents and voltages in three-phase reference frame, the rotor flux components are determined in the Clarke two-phase reference frame as a function of the components of the rotor and stator supply current and voltage components in the Clarke two-phase reference frame and of a correction for the non-linearities of these components, and the electrical angle is determined as being the arctangent of the ratio between the two rotor flux components expressed in the Clarke two-phase reference frame.</p> |
