Differente control techniques for double star induction machine drive under GUI/Matlab

This paper presents a comparison between two control strategies, field oriented control (FOC) and sliding mode control (SMC). The first study has been done on controlling the double star induction machine (DSIM) by using field oriented control technique using a PI regulator. After, we present the theory of sliding mode control. We can see from the simulation results that the second proposed control system (SMC) is a robust nonlinear optimal controller. In order to reduce a torque ripple, the sign function is used, that is will be more explained in this paper. This present work was performed and simulated using our graphical interface `GUI' realized under MATLAB.
