•A field oriented control applied to a double star induction machine is presented.•We propose a decoupling bloc structure based on fuzzy logic controllers.•We compare two field oriented control structures.•We analyze the control performance upon rotor resistance variation.•Field oriented control based on fuzzy logic controllers provides a high robustness. The difficulty of control in the induction machine is due to the coupling of the torque and flux since the load torque change induces unavoidably the flux variation. So, to ensure separately the control of these two variables, the field oriented control is often used. Also, the efficiency of the latter technique is closely related to the conventional proportional integral controller parameters. Evidently, it is suitable to use controllers which are independent of the parameters variations as an alternative solution. For this purpose, fuzzy logic controllers associated to the indirect field oriented control (IFOC) of a double star induction machine (DSIM) are then used and the performance of the system is finally tested under different operating conditions. The results obtained in MatLab/Simulink environment are presented and show that the proposed structure of control is more robust and non-sensitive versus the rotor resistance variation of the machine.
