Abstract
The control problem of the motor driven joint system under the state and input constraints is discussed in this paper. Firstly, a state transform function is introduced to transfer the state-constrained motor driven joint system to a transformed system, which no longer has the state constraints. Secondly, an adaptive robust control (ARC) with the specified performance bounds is proposed for this transformed system, where the ARC algorithm combined with an auxiliary variable are used to ensure the semi-globally uniformly ultimately bounded of all the closed-loop signals, and a time-varying barrier Lyapunov function (BLF) is designed to constrain all the tracking errors within the specified performance bounds. Thirdly, the above results are extended to the motor driven joint system. Namely, the boundedness of the states in the transformed system are converted into the satisfaction of the state constraints in the motor driven joint system, and the fast transient response and high steady-state tracking accuracy can be achieved by designing the appropriate specified performance bounds in the time-varying BLF. Finally, a simulation is carried out, and the results demonstrate the effectiveness of the proposed method.

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 it
