Autodisturbance rejection controller in direct torque control of permanent magnet synchronous motor drives
Bibliographic record
Abstract
The nonlinear extended state observer (ESO), which is the key part in composing an autodisturbance rejection controller (ADRC), becomes the most active method in the field of modern control theory. It can be used in the direct torque control (DTC) of permanent magnet synchronous motor (PMSM) to improve the robustness of the system, reduce the torque ripple and decrease speed drop when load is increased instantaneously. ADRC can rapidly and accurately reconstruct the information of the plant perturbations of parameters and external disturbances. Based on this information, feedback linearization can be achieved by proper designed compensation. In this paper, the traditional DTC control of PMSM is improved in both the DTC itself by increasing the torque and flux controller output variables and system robustness by adopting ADRC. Simulation and experimental results are provided to verify the proposed 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.
