Abstract
This paper presents a finite-time switching resilient controller for the networked teleoperation system control under time-varying delays and denial-of-service (DoS) attacks. The proposed controller comprises a proportional-differential plus damping (PD+d-like) controller and a switching resilient compensator. The first component, a PD+d-like controller, uses a continuous non-smooth function on the state errors and velocity signals to guarantee the global finite-time convergence. The latter part of the proposed controller, a switching resilient compensator, combines the zero-order holder (ZOH) with the continuous-time proportional-derivative (PD) regulator. This proposed controller could maintain global finite-time stability (GFTS) when time-varying delays and random DoS attacks simultaneously occur. Furthermore, we obtain the system stability criterion and establish relationships between controller parameters and maximum stability delay using Linear Matrix Inequality (LMI) technology for parameter tuning guidance. Both simulation and experimental results validate the resiliency of the proposed controller to time-varying delays and random DoS attacks.

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
