Abstract

fetched live from OpenAlex

This study is concerned with observer design for a class of Lipschitz nonlinear systems. A high-gain observer with a straightforward structure is proposed. As opposed to the well-known high gain observers, dynamic gains obtained are used to reduce the effect of peaking. In addition, the injection term of the observer is passed through a linear filter to reduce its sensitivity to noise. It is shown that the suggested observer is peaking free with respect to the initial conditions, while achieving the input to state stability with respect to measurement noise, as a HGO. The analysis of the steady-state response also shows that the proposed observer performs better in the presence of high-frequency noise. The simulation results compare the performance of the proposed method with some existing observers.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
