Abstract
This paper presents a power control strategy for a fixed-pitch cross-flow hydrokinetic turbine (HKT) which operates at low rotational speed region (stall region) and maximum power point tracking. The suggested system uses a permanent magnet synchronous generator (PMSG), a diode rectifier, a boost DC-DC converter which is connected to a DC microgrid. Power control of the HKT is obtained by controlling the duty cycle of the boost DC-DC converter. This method employs an inner voltage loop to stabilize the system in the stall region and an outer power control loop to regulate the diode rectifier DC-link power. The suggested control strategy has the capability to adjust the HKT output power from zero to maximum available power for the complete operating range up to the cut-out water speed. The control system is designed and developed based on a linearized model of the system. The proposed strategy is experimentally verified with an electromechanical-based HKT emulator.

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
