Vold-Kalman Filtering Order Tracking Based Rotor Flux Linkage Monitoring in PMSM
Bibliographic record
Abstract
Monitoring permanent magnet (PM) flux linkage is important to maintain a stable permanent magnet synchronous motor (PMSM) operation. In this paper, V old-Kalman filtering order tracking (VKF-OT) and dynamic Bayesian network (DBN) are used to investigate the application of torque ripple in real-time PM flux monitoring. Firstly, a torque ripple model of PMSM considering electromagnetic noise is proposed, and the torque variation is studied. In this model, the torque is analyzed and processed by wavelet transform to eliminate the effects of the electromagnetic disturbances. Secondly, VKF-OT is introduced to track the order of torque ripple of PMSM running in unsteady state. Therefore, torque ripple characteristics can be used as a feature to reflect changes in PM flux linkage. Thirdly, this method is feasible for PMSM by applying DBN to the training data to estimate the flux linkage during motor operation. The proposed flux monitoring method is validated on a laboratory PMSM. The results demonstrate that this method can monitor the flux variation over a wide speed range at different load levels.

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.
