SYSTEM AND METHOD FOR CONTROLLING AN ELECTRIC MACHINE LIMITING ITS ENTRY IN DEGRADED CONTROL MODE

摘要

The invention relates to a system (SYS) for controlling an electric machine (ME) with wound stator and rotor, comprising: - a first mapping (CART1) of currents minimizing the electrical losses in the machine (ME), - a second mapping (CART2) of currents, minimizing the rotor electrical losses, - a third mapping (CART3) of currents minimizing the stator electrical losses, - a selection means (MS) of a mapping as a function of the rotor temperatures (Tr) and the stator (Ts), for supplying 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 a means for inhibiting (MI) the delay means (MT) beyond a predetermined time when the new mapping is the first mapping (CART1).
