According to the method of the invention, the estimation of the angular position is obtained by calculating at least one first estimator as solution of a differential algebraic equation whose coefficients depend on electric parameters of the rotating electric machine comprising first and second inductances of a stator respectively along a direct axis and a quadrature axis with respect to a magnetic flux produced by the rotor of the machine, a resistance of a phase winding and the magnetic flux produced by the rotor. The coefficients also depend on a reference voltage of a vector pulse width modulation (10) applied to the stator of the machine, on phase currents and on first derivatives with respect to time of these phase currents. The estimation of the speed of rotation is obtained by calculating a second estimator obtained by a calculation of first derivative of the first estimator with respect to time. |
