Abstract

fetched live from OpenAlex

This paper proposes an adaptive neural fault-tolerant approximated inverse control for a class of fractional-order (FO) nonlinear hysteretic systems. First, by co-designing the approximated inverse method and adaptive neural laws, the controller compensates hysteresis in the FO nonlinear hysteretic systems and maintains precise tracking under actuator and sensor faults. Then, combine the FO Nussbaum-type function with a coordinate transformation, the unknown fault gains are ingeniously handled. Additionally, the FO dynamic surface control (FODSC) scheme has applied which solve the "computational complexity" issue for FO backstepping (FOBS) method. Finally, the effectiveness of the proposed control strategy is validated through a simulation example.

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.
