Abstract—This paper investigates a fuzzy speed sensorless vector control of Dual Star Induction Motor (DSIM) using MRAS approach. The rotor flux and speed estimator based on a PI model reference adaptive system (MRAS) is developed. The error in the instantaneous phase position of the two rotor flux estimates is utilized for rotor speed estimation. In order to achieve high performances in term of fast dynamic speed response and best disturbance rejection, fuzzy logic controller (FLC) is used for speed regulation. The proposed scheme is recommended for applications requiring robust speed control even in presence of some key parameters deviation. The performance of the suggested scheme has been tested through some simulation results.
