MIMO SLIDING-MODE AND H∞ CONTROLLER DESIGN FOR DYNAMIC COUPLING REDUCTION IN UNDERWATER-MANIPULATOR SYSTEMS
Bibliographic record
Abstract
In underwater remote vehicle-manipulator system (URVM) applications, it is beneficial to have the underwater remote vehicle (URV) hold station using its thrusters while a human pilot operates the serial manipulator. This provides a stable platform for the manipulator and eases the pilot’s job drastically when current and/or tether disturbances are present. The contribution of this work is twofold: Firstly, the reduction of dynamic coupling in the URVM systems is realized using two robust control techniques namely Sliding-mode control and H ∞ control, and the performance of both controllers in the dynamic coupling reduction problem is reported. Secondly, a new control scheme is proposed that involves both controllers in the control loop. Numerical case studies are developed to demonstrate the effectiveness of the controllers. It is concluded that sliding-mode and H ∞ controller combined approach provides superior dynamic coupling reduction performance.

Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
