Abstract: the method and carried out the synthesis of the ID of the coordinate system field-oriented  control of asynchronous  electric drive with the  structure calculations, a uniform  for the orientation system according to one of the vectors of the flux  of the stator, the magnetic  gap or the rotor;  study on the identification accuracy  when the variations of the parameters of the induction motor from the nominal tuning values for the ID.

Keywords:  synthesis, mathematical model, algorithm, information-sensor system, field oriented control, the orientation of the coordinate basis, the ID, modeling, identification errors.
