Abstract
A process for controlling a variable-reluctance synchronous electric motor is implemented in a processing unit coupled to a power converter connected to the electric motor. The process includes a phase of identifying a flux inductance value of the electric motor, which includes a step of generation of a reference current (īd) at the input, for each reference-current value (īd), a step of determination of a current value (īd) in the output phases, for each reference-current value (īd), a step of determination, by an identification module, of an inductance value (īdEST) as a function of a reference-current value applied at the input, of the corresponding current value measured in the output phases, and of a predetermined or variable inductance value ({circumflex over (L)}d).
