Abstract
This study deals with the problem of controlling rotor speed and stator currents of an asymmetrical six‐phase induction machine with uncertain dynamics, disturbances, and unmeasurable rotor currents and proposes a robust non‐linear variable structure controller. First of all, an outer control loop based on a proportional–integral regulator is performed to control the rotor speed and to construct the desired stator current references. Then, the inner loop is performed based on the proposed method that combines the time delay estimation method and discrete sliding mode control based on exponential reaching law. This structure allows an accurate and simple estimation of uncertainties and rotor currents, a high‐tracking precision, a convergence of the stator currents to their known desired references in finite‐time and chattering reduction. The design procedure is detailed step by step and the stability analysis and the convergence time are established for the current closed‐loop system. Experimental work was carried out on an asymmetrical six‐phase induction motor drive to show the effectiveness and performance of the proposed robust non‐linear discrete method. The results obtained highlighted the good tracking performance of the stator currents.

Full frame distilled prediction
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
