“…To show the improvement in the proposed control over other proposed methods in the literature [6,23,24,[29][30][31], a comparison between the C-DTC, 12-DTC, and the proposed F12-DTC was made and is presented in Table 5 and Figures 24 and 25a Table 5 presents the electromagnetic torque ripples and rotor flux ripples during the three DFIG operating modes and the overspeed case, as well as the rate of improvement in torque and flux-ripple reduction controlled by the proposed F12-DTC compared to both C-DTC and 12-DTC. As shown in this table, the ripples of both torque and flux are important in the studied system controlled by C-DTC and 12-DTC compared to the proposed F12-DTC.…”

“…The direct-torque-control-based twelve sectors methodology has been introduced to control doubly fed induction machines for both motor and generator operations without any driving in [23] and to control DFIG driven by WT in [24]. In these references, researchers analyzed the performances for variable mechanical speed dealing only with the subsynchronous mode, where the super-synchronous and synchronous modes and the overspeed were not investigated to show DFIG's benefits in terms of performance improvement.…”

“…On the other side, the null voltage vectors (V 0 and V 7 ) that concern H Tem = 0 (when the torque must be maintained) were added compared to the switching table used in [23,24] to have more control precision. In Figure 6, the variation in torque and flux was influenced by the voltage vectors in different manners.…”

“…All those modifications in SVM-DTC, P-DTC, sliding-mode-DTC (SM-DTC), and ML-DTC techniques increase the complexity of the control system and lose one of the C-DTC benefits: its simplicity. Recently, researchers in [23][24][25][26][27] have proposed to use the same principal of C-DTC, hysteresis regulators, and switching table but reducing the size of each sector from 60 • to 30 • , which will increase the number of sectors from 6 to 12 and will rise the degrees of freedom for the selection of the rotor voltage vector. Thus, the switching table will be modified with more rules; this will improve the control accuracy, while keeping the simplicity of the control system.…”

A wind turbine (WT)-based doubly fed induction generator (DFIG) is the most often used generator in the wind conversion system market due to its advantages such as the ability of operating under variable wind speed and its high performance. However, nonlinear dynamical and parameter uncertainties of the DFIG make the controller design of this kind of system a challenging work. Thus, in this study, a novel control strategy was proposed to design the desired system dynamics, to highlight the efficacy of the proposed system, and to improve the performance of the closed-loop system. The proposed controller combines the twelve-sector direct torque control (12-DTC) and the fuzzy controller with modified rules to solve the limitations and shortcomings of the usual methods for the WT-DFIG system. All operation modes, successively and continually, were considered to reflect the true operation of WT-DFIG system subject to random wind speeds. The aims of this work was to ensure an optimal operation of the wind generator, extracting maximum power in the zone II of the WT characteristic, and limiting this power in its maximum value in the case (zone III), to transmit the power generated by the DFIG to the grid-side with minimum losses in the disturbances related to DFIG. Extensive numerical simulations were performed under MATALB/Simulink, where the proposed fuzzy twelve direct torque control (F12-DTC) was compared with conventional nonlinear controls: conventional DTC (C-DTC) and 12-DTC. The simulation results demonstrated clearly that the proposed one had the highest performance and robustness, with a significant reduction in rotor flux and electromagnetic torque ripples and better-generated power quality with low currents’ THD over the conventional strategies (C-DTC and 12-DTC).
