Abstract
The present invention relates to a method and a system for correcting references (xref), in the case of flux reduction, used in a speed variator for controlling an electric motor M having a three-phase supply, for example of the synchronous or asynchronous type.This method consists, in particular, of using a dynamic system (MM) representing a model of the motor to be controlled, provided with at least one integrator (Int) and having as input the difference between a limited value of a control voltage (u) to be applied to the motor (M) and the value of a calculated reference voltage (uref).
