This paper is dedicated to controlling the speed of the double star induction machine (DSIM) by a robust controller. The model of DSIM has been presented by using a vector representation. To control this machine, three robust nonlinear controllers have been used: an active disturbance rejection control (ADRC) regulator is presented in the first place, after a sliding mode control (SMC) is studied in second place, to achieve some performance for the machine, and then followed by the proposed robust controller based on the Backstepping (BSC) technique, this technique is based on the stability of the Lyapunov function. A comparative study between these controllers (ADRC, SMC and BSC) has been presented. The performance of three regulators or three techniques is evaluated under the normal operating condition of the machine and in the presence of one current sensor fault. The simulation of these techniques is presented, the results showed that the proposed controller based on BSC is more robust than that of ADRC Controller and SMC controller.
