Abstract

fetched live from OpenAlex

Modifications and design of an algorithm for identifying the frequency of periodic signal or disturbance are studied in this paper. The approach utilizes a feedback control system and can achieve true frequency estimation without error in the steady state. High frequency ripple has been observed in the frequency estimate of the original algorithm. This problem is analyzed on a theoretical basis in the paper. An alternative solution is presented to eliminate this ripple other than the previous adaptive notch filter approach. The design issue of the algorithm is also discussed in this paper, especially when multiple frequency components are present in the input signal. LQR optimal control technique is employed in determining the feedback gains in the estimation system. Simulations are conducted and results are presented.

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.
