Abstract

In this paper, we studied the vector control, by orientation of rotor-flux by using fuzzy regulators for an induction machine without speed sensor with adaptation of rotor resistance. The speed is estimated by using the adaptive method with model of reference (MRAS). This method consists in working out two models one of reference and the control adjustable one for the estimate of two components of stator flux starting from the measurement of the currents and stator voltages. The estimated speed is obtained by cancelling the difference between stator-flux of the model of reference and those of the adjustable model. Very satisfactory results of simulation are presented at the end of this paper.
