Digital Sliding-Mode-Based xy-Current Suppression in Dual Three-Phase PMSM Drives
Bibliographic record
Abstract
This paper presents a digital sliding-mode-based current regulator for the suppression of the undesirable circulating currents in a dual three-phase (DTP) permanent magnet synchronous machine (PMSM) drive. Due to their high frequency variation in synchronous reference frame and non-linear inductance variation, the suppression of the circulating currents is a challenging task. Following the principles of digital sliding-mode control, the proposed controller is capable of effectively suppressing the circulating currents. The performance evaluation of the proposed controller is performed in two modes, viz, equivalent control law based and equivalent control law with disturbance compensation. The former ignores the effect of inherent disturbances while the latter uses a simple unit time-steps delayed disturbance approximation. In this paper,the performance of both methods is compared to a conventional PI regulator in MATLAB/Simulink, and simulation results are verified experimentally. It is proved that the two proposed methods have better performances compared with PI controller.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
