<p>This manuscript provides a new fault ride-through approach for doubly fed induction generator-based wind energy system under both severe unsymmetrical and symmetrical grid fault circumstances. To enhance dynamic response and fault resilience, an advanced controller is proposed by integrating a super-twisting sliding mode-based extended state observer into an active disturbance rejection control framework. The proposed hybrid controller significantly improves the conventional active disturbance rejection control structure by enabling fast transient response, robust disturbance rejection, and effective attenuation of high-frequency measurement noise during critical fault scenarios. Extensive time-domain simulations and case studies are conducted for typical grid fault conditions, including unsymmetrical faults like line-to-ground, line-to-line, and three-phase symmetrical faults. The results demonstrate that the proposed control strategy outperforms conventional proportional-integral and linear active disturbance rejection controllers in terms of rotor current suppression, DC-link voltage stabilization, and rapid voltage recovery. Moreover, the controller ensures smooth system operation without compromising stability. To further validate the real-time performance and feasibility of the proposed method, a hardware-in-the-loop experimental setup using the dSPACE ds1104 platform is developed. Experimental results closely match simulation outcomes, confirming the superiority of the proposed control system in achieving enhanced fault ride-through capability under grid disturbances. This research contributes a robust and practically viable control solution for a resilient doubly fed induction generator-based wind power system.</p>
