A New Model Predictive Control Formulation for CHB Inverters
Bibliographic record
Abstract
The finite control model predictive control (FCS-MPC) is considered one of the most important advances in power converter control. MPC offers the power converters with high dynamic performance, multi-objective capability, and no need for modulation schemes or tuning of PI parameters. It was reported that longer prediction horizon MPC yield better performance than short prediction horizon MPC. However, the number of computations increases significantly when real-time implementing long prediction horizon MPC on a multilevel power converter due to the existence of a huge number of switching combinations and redundancies. To overcome this bottleneck, this paper has presented a FCS-MPC scheme. In the proposed method, instead of estimation all the possible switching combinations in each sampling step, the multistep FCS-MPC is reformulated mathematically to an optimization problem, which can be solved through matrix theory. Compared with the existing MPC optimization algorithms, the proposed prediction formulation method has the advantage of reduced computational burden and no need for the cost function. The proposed method is finally verified on a seven-level CHB inverter.

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.
