The present invention relates to a method for the quick-response control of a synchronous motor having "buried" permanent magnets, this method consisting in applying, by an inverter supplying the motor, and over a calculation period T, a voltage vector for obtaining, after the period T has expired, a mechanical force developed by the machine equal to a predetermined setpoint, and comprising the following steps: calculation of an eigenvector corresponding to the initial state of the motor representative of the stator current vector and of the magnet flux vector in the initial rotating rotor reference frame at the start of the period T; generation, in the predicted rotating rotor reference frame, of a setpoint current for achieving the determined setpoint at the end of the period T; generation of an eigenvector corresponding to the setpoint state of the motor representative of the setpoint current and of the predicted magnet flux vector in the initial rotating rotor reference frame at the end of the period T; calculation of the voltage vector in the fixed stator reference frame to be applied by the inverter to the motor in order to control it; and application of the voltage vector to the motor by the inverter in order to obtain a current equal to the setpoint current after the period T has expired. |
