Nonlinear model predictive control for trajectory tracking of an AUV: A distributed implementation
Bibliographic record
Abstract
This paper investigates the nonlinear model predictive control (NMPC) method for the trajectory tracking application of an autonomous underwater vehicle (AUV). To formulate the tracking control problem into the standard MPC scheme, the desired spatial reference trajectory is augmented according to the kinematic property of the AUV motion, which facilitates the following distributed model predictive control (DMPC) implementation. Considering that the computational complexity of the nonlinear programming (NLP) problem associated to the NMPC tracking control could be prohibitively high, the DMPC implementation is proposed attempting to alleviate the computational burden. The six degree of freedom (DOF) AUV model is then decomposed into three slightly coupled subsystems, and the DMPC subproblems are well defined with the original cost function broken down appropriately. Warm start strategy is adopted to enhance the control performance. Simulation studies are carried out, which verifies the effectiveness of the proposed method.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
