摘要
The invention relates to a system (SYS) for controlling a wound stator and rotor electric machine (ME), comprising:a first mapping (CART1) of currents minimizing the electrical losses in the machine (ME),a second cartography (CART2) of currents, minimizing rotor electrical losses,a third mapping (CART3) of currents minimizing the stator electrical losses,a selection means (MS) for mapping, as a function of the temperatures of the rotor (Tr) and the stator (Ts), to feed the electric machine (ME),a delay means (MT) of the selection means (MS), as long as a torque setpoint (T) remains above a threshold,and means for inhibiting (MI) the delay means (MT) beyond a predetermined time when the new map is the first map (CART1).
