Nonlinear control of FACTS and HVDC belonging to the voltage-source converter family
Bibliographic record
Abstract
The nonlinear control method, associated with the books of A. Isidori (1989), and H. Nijmeijer and A. J. van der Shaft (1990), has so far been applied to the STATCOM (system order, N=3). There have been two hindrances to progress: (1) synthesizing the nonlinear transformation function which is the key to the method; (2) unfamiliarity with the advanced mathematical language. This paper describes the successful application off the method to the unified power flow controller (UPFC) (N=5). The paper is written in a tutorial form to give insights into how the nonlinear transformation function can be synthesized for voltage-source converters, where the bilinear nonlinearity has its origin from the power balance equation relating the ac-side power to the dc-side power. The objective is to explain the method in more accessible mathematical language so that more power electronic engineers can also use the nonlinear control method

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
