Abstract

fetched live from OpenAlex

In this work, a Variable Structure Control (VSC) system is developed to remove the instability of an articulated steer vehicle during the snaking mode. First, by using a linearised model of the vehicle, the equations of motion are derived in the state-space form. The uncertainties in the tyre-road contact parameters introduce some unknown and time-varying but bounded terms to these equations. This will be a basis for designing a robust VSC system to stabilise the vehicle during the snaking by a torque vectoring device. The robustness of the resulting controller is examined for different driving conditions in terms of the road surface, forward speed and vehicle parameters, based on the linearised model. The control system is also incorporated into a virtual prototype of the vehicle in ADAMS, and its operation is investigated. The results from the linear model analysis and simulations in ADAMS show that the controller can eliminate the instability effectively.

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.
