METHOD AND DEVICE FOR CONTROLLING A ELECTRIC MOTOR PROPULSION UNIT WITH DECOUPLED CONTROLS

摘要

Method of controlling an electric motor furnished with a rotor and a stator, sensors for measuring currents flowing in the rotor and in the stator, means for determining setpoints of current and means for processing the signals from the measurement sensors, characterized by the fact that it comprises steps in the course of which: intermediate signals are determined 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 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 are determined as a function of the intermediate signals obtained by transformation.
