Abstract :Direct torque control insert ignore into journalissuearticles values(DTC); of Doubly Fed Induction Machine insert ignore into journalissuearticles values(DFIM); has large torque ripples and inconstant switching frequency, especially at low speed. This paper proposes an enhanced DTC method based on fuzzy logic technique. In order to improve the drawbacks of this conventional DTC and overcome the robustness problems against parametric variations of the DFIM, the switching tables and conventional PI regulator of speed are elaborated by the reasoning of fuzzy logic. A very detailed analysis of simulation results of the system in Matlab/Simulink environment is performed to the regarding to speed variation, reference tracking and robustness against system parameters variations. These results show the efficiency and robustness of this fuzzy logic controller for enhancing the performance of the DTC control of DFIM.
