Abstract: This paper presents, first a d-q purely mixed model including the mutual leakage flux and a digital field oriented control of a double star induction motor using a two-level six-phase inverter; seconds a PI regulator to control the speed and the stator current of DSIM. To achieve a control of this machine two voltage source inverter of PWM techniques are introduced. A comparison with a traditionally (PI) controller is discussed. Extensive simulation is performed and it is shown that the reduction of the current harmonics is in essence almost the same as in another recently developed DFOC scheme. However, the achieved torque ripple reduction makes the scheme superior when compared to the existing approaches. At the same time, developed scheme retains qualities of conventional DFOC schemes, such as simple structure and fast response. Its additional beneficial feature is the easiness of implementation.
