Discrete Vector Control for Induction Motor Drives with the Rotor Time Constant Update

Authors: A.Larabi, M.S. Boucherit


In this paper, we investigated vector control of an induction machine taking into account discretization problems of the command. In the purpose to show how to include in a discrete model of this current control and with rotor time constant update. The results of simulation obtained are very satisfaisant. That was possible thanks to the good choice of the values of the parameters of the regulators used which shows, the founded good of the method used, for the choice of the parameters of the discrete regulators. The simulation results are presented at the end of this paper.

Keywords: Induction Motor, PWM, discrete vector control, PIRegulator, transformation of park
