Abstract
This study presents an overall sliding mode control scheme for stator power‐current control, grid power‐current control and dc‐link voltage regulation to operate a doubly‐fed induction generator (DFIG) based wind energy conversion system. At the generator rotor side, the stator power control is achieved through controlling the rotor currents. The rotor current state model is carried out from the stator and the rotor equations of the generator under the condition of stator voltage alignment. At the grid side, a cascade control loop is applied for the dc‐link voltage regulation and the power transfer using grid and dc‐link modelling. The structure of the sliding mode control law, combination of compensating, sliding and integral terms, enhances the tracking performance and the robustness to uncertainties. The proposed control strategy is validated using an experimental DFIG wind turbine system and the results are provided to demonstrate the capabilities of the proposed control system in tracking and control under different operating conditions and robustness to uncertainties.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
