Abstract
The Hall-sensor-controlled brushless dc (BLDC) motors are often considered in low-cost applications due to their simplicity of control and good performance in a wide range of operating conditions and speeds, where they still may be preferred over more complicated sensorless controls. Due to a possible failure of Hall sensors, there has been an increased interest in fault-tolerant-control (FTC) in the literature. However, most established FTC methods are not capable of fast fault diagnosis and compensation, which may lead to degradation of dynamic performance, especially during transients. This article proposes an improved fast FTC (FFTC) that obtains fast identification and compensation of asynchronous or simultaneous faults of up to two Hall sensors. The proposed FFTC method is validated experimentally and shown to maintain continuous operation even under extreme dynamic accelerations and sudden load variations, which are the advantages over alternative FTC methods.

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 it
