Abstract
A method of controlling an electric motor including a rotor and a stator, sensors for measuring currents flowing in the rotor and in the stator, a mechanism determining setpoints of current, and a mechanism processing the signals from the measurement sensors, the method including: determining intermediate signals by a transformation according to which stator voltages and rotor voltages of the electric motor are expressed in a decoupled reference system as a function of the signals received from the processing means, and determining signals for regulating voltage as a function of the currents flowing in the rotor and in the stator of the electric motor satisfying the setpoints of current as a function of the intermediate signals obtained by transformation.
