Speed sensorless vector control of double star induction machine using reduced order observer and MRAS estimator

Abstract

In this paper, two approaches to speed estimation, presented in the literature, for a sensorless control of double star induction machine. We will discuss briefly the advantages, disadvantages, and limits of use of these techniques. We will then apply these two sensorless control techniques to the double star induction machine. The simulation results obtained showed that the speed sensorless vector control of a DSIM is robust to the load disturbances and/or the change of the reference speed. The proposed control scheme is verified by the simulation.
