Abstract
A method controlling a powertrain fitted in an automobile and including an electric motor including a rotor and stator, the method including: regulation of currents of the rotor and the stator via control signals from the electric motor, wherein the currents and control signals are expressed in a rotating coordinate system and include a plurality of axes, the control signals resulting from a first transformation including a change of variable that enables dynamic decoupling between the control signals, along each of the axes of the plurality of axes; saturation of the control signals resulting from the first transformation to satisfy constraints of a battery fitted in the automobile and connected to the electric motor; and blockage of at least some of the current reference values of the regulation if the control signals are saturated.
