“…However, the DFIG is subject to the effects of parametric uncertainties (due to saturation, overheating ...) and the effect of disturbance due to the speed variation, which could deflect the system from its optimal operate. This is why the control should be concerned with robustness and performance [4]. To do this, we referred to the use of the robust control.…”

In this paper, we propose a new control strategy called linear active disturbance rejection control (ADRC) used to control the wind energy conversion system (WECS) based on doubly-fed induction generator (DFIG). This recent control strategy is compared with the conventional RST polynomial control method considered better and more efficient than the classical PI method according to different works. By the extended state observer ESO of the ADRC controller, the internal and the external disturbances on the system are estimated and compensated as a total disturbance in real time. Moreover, the proposed ADRC method is easy to tune and more practical which has only one tuning parameter. The RST controller has three polynomials chosen in order to reduce the effect of disturbance. These controllers have been used to control the stator powers of DFIG in order to extracting the maximum energy produced by the wind by using a maximum power point tracking (MPPT), to regulate the dc-link voltage in order to maintain DC bus voltage at constant value and to regulate the reactive power to ensure a unitary power factor. Then, these both control strategies are designed and their performances are compared in order to deduce the most efficient in terms of reference tracking and robustness. The simulation results prove that the proposed ADRC control technique is more robust and have better performance than the RST control.

Summary This article deals with the improvement of maximum efficiency schemes of doubly fed induction generator–based wind turbines (DFIG‐WTs) through controlling their rotor current. The nonlinearity characteristics, parameters uncertainty, and grid disturbances in the DFIG‐WTs may affect the tracking performance and the energy conversion efficiency. The magnetizing inductance has the highest value, compared to the other DFIG parameters. Also, its value varies during grid disturbances due to main flux saturation. Therefore, improper setting of its value in the controller can result in significant performance distortion. Active disturbance rejection controller (ADRC) is a simple and robust control technique that can deal with the system's internal and external disturbances. Besides, ADRC does not strongly depend on the accurate mathematical model of the system. For further improvement of the response speed of the traditional ADRC, a novel control strategy based on a model‐assisted ADRC (MA‐ADRC), considering the variation of the magnetizing inductance, is proposed to regulate the rotor current. Furthermore, a new tuning approach is suggested to evaluate the parameters of the MA‐ADRC. Response of the presented strategy is assessed on a 1.5 MW DFIG‐WTs using MATLAB/Simulink package. The proposed MA‐ADRC is compared with the traditional proportional‐integral (PI) controller and existing ADRCs strategies under various scenarios. The simulation results validate the precise tracking performance of the suggested strategy and its robustness against grid disturbances and wind speed variations.
