A robust nonlinear controller for a StatCom based on a 3-phase neutral point clamped converter
Bibliographic record
Abstract
This paper presents a three-level three-phase diode clamped inverter that uses an auxiliary circuit to equalize its DC-bus capacitor voltages. The proposed converter is used in a static compensator (STATCOM) and a controller is designed for this new STATCOM. A state space model of this compensator connected to a grid is obtained first. Three single input single output (SISO) robust controllers are designed to control the StatCom terminal voltage, to regulate the DC-bus voltage and to equalize the capacitor voltages. The effectiveness of the control strategy is guaranteed by the fact that each of the SISO controllers is provided with appropriate nonlinear terms that compensate the interactions between the STATCOM sub-modules. The STATCOM performance is evaluated. The results demonstrate that it is capable to maintain its terminal voltage and its DC-bus voltage at their reference values while equalizing the capacitor voltages despite significant variations of grid parameters.

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.
