The aim for this paper is a proportional and integral (PI) controller and fuzzy logic (FLC) controller devoted to improve the performance of Direct field orient control (DFOC) strategy of doubly star induction motor (DSIM) fed by two inverters. In addition, the paper describes a model of doubly star induction motor in d-q reference frame theory and its computer simulation in MATLAB/SIMULINK®, fed by Pulse Width Modulation (PWM) inverter to be studied. The performance of the Direct Field orientated control with a PI and FLC is tested under different speed command and load disturbances. And also show a better robustness beside the parametric variations of the motor.

The main disadvantage of the classical direct torque control is high torque and flux ripples. This is due to hysteresis comparators suffer from a variable switching frequency and a high torque ripple. Besides, a hybrid strategy; Direct Torque Control with Space Vector Modulation (DTC-SVM) is established using Interval Type-2 Fuzzy Logic Controller (IT2FLC) for enhancing control performance parameters to reducing torque and flux ripple. In this work, a IT2FLC is applied to the DTC-SVM of Double Stator Induction Machine (DSIM). Simulation results are shown to present the robustness and efficiency of the recommended control strategy.

This paper concerns the study of a direct torque control based on fuzzy logic type-2 for the speed regulation of a doubly star Induction Machine fed by voltage source inverter. This command has become one of the high performance control strategies for AC machine to supply a very rapid torque and flux control. The proposed technique consists to change the proportional and integral controllers by type-2 fuzzy logic controller. The performance of the scheme in different operating conditions is studied. Particular interest is given to the robustness of the fuzzy logic based control. Furthermore, the simulation results illustrate the efficiency and robustness of the type-2 fuzzy logic controller.

The aim of this article is to improve the performance of the classical direct torque control (DTC) of doubly star induction motor (DSIM) drive by reducing the ripples level in electromagnetic torque and stator flux. For this reason, we present different strategies to enhance the performance of DTC such as DTC_SVPWM. This technique replaces hysteresis controllers by two (PI) controllers to generate the direct and the quadrature voltage components in d-q frame. However it is difficult to adjust the parameters of PI controller due to the complexity of the control system. The self-tuning PI fuzzy controller was proposed to adjust the PI parameters in this paper. Simulation is carried out using MATLAB/SIMULINK and the performance of the proposed fuzzy system is analyses. The simulation results show that the proposed method can significantly reduce the torque ripple and is suitable for various motor at different working state.
