Direct torque control (DTC) of Doubly Fed Induction Machine
(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.
