Abstract

fetched live from OpenAlex

AC–DC matrix converter is a kind of bidirectional converter features buck-type rectifying and boost-type inverting. Considering the coupling of ac current and dc current, and the requirement on safe commutation, the finite control set model predictive control (FCS-MPC), featuring multiple-objective capability and direct generation of gating signals without pulse width modulation (PWM) scheme, is very suitable for this topology. Also, fast transient can be obtained with the FCS-MPC. However, in conventional FCS-MPC, only one space vector in each sampling period is applied. The performance will be degraded due to the low switching frequency under limited sampling frequency in practice. In this article, an FCS-MPC with virtual space vectors is proposed for a bidirectional ac–dc matrix converter. This article uses several virtual space vectors, each formed by two real space vectors, to improve the control performance without increasing sampling frequency. To further reduce the computation burden, an efficient method to preselect space vectors is proposed. Furthermore, a thorough analysis of the effect of parameter mismatch in the proposed FCS-MPC is conducted to ensure robust performance. Both simulation and experimental results are presented to verify the effectiveness of the proposed control strategy.

Teacher imitation

Not 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.
