Abstract
The development of a dead-beat current controller with a disturbance estimator for grid-connected single phase (1ϕ) voltage source (VS) inverter is presented in this paper. The 1ϕ VS inverter is connected to the grid using L-type filter. Disturbance estimator is employed to reject any disturbances due to controller time delay, inductance mismatch, and/or grid voltage disturbances. The design and analysis of the proposed controller is verified using simulation. Moreover, experimental testing under several disturbance conditions is carried out using 10 kW grid-connected 1ϕ inverter. The traditional predictive current controller is also tested with the same disturbance conditions to demonstrate the advantages of the proposed controller. Experimental results show the capabilities of the proposed controller in rejecting disturbances and maintaining the grid current at the command value.

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
