Abstract

fetched live from OpenAlex

This paper is concerned with event-triggered robust model predictive control (MPC) for linear discrete-time systems with bounded disturbances. The proposed feedback law is based on a convex combination of multiple controllers, involving an LQR controller and a set of low-gain controllers. An event-triggered condition for the combination coefficients is established based on the distance between the actual state and a robust positively invariant set. The proposed co-design of the event-triggered scheme and the feedback policy leads to a larger terminal region and a longer average inter-execution time with guaranteed recursive feasibility and robust stability. An example is used to demonstrate the effectiveness of the proposed method.

Teacher imitation

Not 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.
