Abstract: The paper considers the task of simulation of the rotor flux control system dynamics in the rotor flux oriented vector control system of the induction motor with application of the mathematical model in the form of the extended root locus. Control system parameters calculation has been carried out in consideration of the system functioning in conditions of substantial parametric uncertainty. The results of time response simulation confirm small sensitivity of the system to parameter variations.

Keywords: dynamic system, root locus, modeling, robust stability
