Abstract
This article presents a new vector current controller for the grid-connected three-phase voltage-source converter (VSC). The VSC is increasingly used in many applications, such as distributed generation, motor drives, and high-voltage dc (HVdc) systems. From a control system perspective, this presents a two-input two-output coupled problem when transformed into the synchronous rotating reference frame. The common approach is to decouple the two control loops and use two single-input single-output (SISO) controllers. There are also some more recent approaches to treat the problem using multivariable or model predictive techniques. The proposed controller of this article is based on a multi-input multi-output (MIMO) approach that, compared with existing approaches, offers: 1) a significantly improved robust performance and 2) a convenient systematic and optimal design procedure. Details of the proposed approach and multiple simulation and experimental testings are presented to demonstrate the proposed controller.

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
