Background: The direct flux and torque control are a robust, simple, and alternative approach control formulation that does not require decomposition into symmetrical components; the direct flux and torque control schemes have been proved to be preponderant for doubly-fed induction generators due to the simple implementation. Aim: This work presents the minimization of electromagnetic torque and rotor flux undulations of doubly-fed induction generators using fractional-order super twisting algorithms and modified space vector modulation techniques. Methods: The main role of direct flux and torque control is to regulate and control the electromagnetic torque and rotor flux of doubly-fed induction generators for wind turbine systems. The direct flux and torque control is a traditional control algorithm and robust technique. Fractional-order super twisting algorithms are a new and proposed nonlinear controller; characterized by a robust controller and a simpler algorithm, which gives a good harmonic distortion of current compared to other methods. Novelty: The A fractional-order super twisting algorithm is proposed. Proposed nonlinear controller construction is based on the traditional super twisting algorithm and fractional calculus to obtain a robust controller and reduces the electromagnetic torque and rotor flux undulations of doubly-fed induction generators. We use in our study a 1.5 MW doubly-fed induction generator integrated into a single-rotor wind turbine system to minimizes the electromagnetic torque, stator current, rotor flux undulations. As shown in the results figures using fractional-order super twisting algorithms ameliorate effectiveness especially minimizes the electromagnetic torque and rotor flux, and minimizes harmonic distortion of stator current (0.16 %) compared to the traditional control scheme. Results: As shown in the results figures using fractional-order super twisting algorithms ameliorate effectiveness especially minimizes the electromagnetic torque and rotor flux, and minimizes harmonic distortion of stator current (0.16 %) compared to the traditional control scheme. Conclusion: The direct flux and torque control are a robust, simple, and alternative approach control formulation that does not require decomposition into symmetrical components; the direct flux and torque control schemes have been proved to be preponderant for doubly-fed induction generators due to the simple implementation.

“…The particularity of these two techniques is that they are based on the stability of the Lyapunov function and are simple to implement. Direct Torque Control (DTC) is another commonly used control method for controlling torque and flux independently and by going so managing active and reactive power [9]. The presence of significant ripples and the variable switching frequency, which are the main drawbacks of this approach.…”

“…These disadvantages can degrade the quality of the output power. Therefore, Cherifi et al [9] have proposed the Space Vector Modulation to reduce the oscillations observed in the created torque (SVM-DTC). Additionally, Y Benevieri et al [10] have suggested the synchronous DTC for reducing the harmonic spectrum content in the torque.…”

This paper suggests the integral Backstepping nonlinear control of the wind power plant based on the Doubly-Fed Induction Generator connected to the grid in normal conditions and under parameters variation. The stator of the generator is explicitly linked with the electrical network. However, the rotor winding is associated with the grid via a bidirectional AC/DC/AC converter. The purpose of this paper is to control the powers produced by a variable speed wind turbine, pilot the exchanged power between the system and the electrical grid and regulate the voltage of the continuous bus capacitor. Besides, the suggested method is applied to establish the maximum power tracking strategy. The Backstepping control law is established founded on the stability of the Lyapunov function. The proposed control is performed and compared with the conventional Backstepping and the indirect field-aligned control. Discussion of the principle and elaboration of the Integral Backstepping laws are achieved. Performance tests are realized by MATLAB/ Simulink software. From the simulation results, the effectiveness and superiority of the Integral Backstepping are well demonstrated.
