Scalable Outer Approximation of Minkowski Sums of Matrix Ellipsoids for Data-Driven Control

Taira Kaminaga, Hampei Sasahara

Matrix ellipsoids provide a standard framework for representing bounded uncertainties in data-driven control. Since noise models for sequential observations are naturally represent…

Adversarial Destabilization Attacks to Direct Data-Driven Control

Hampei Sasahara

This study explores the vulnerability of direct data driven control, particularly in the linear quadratic regulator (LQR) problem, to adversarial perturbations in offline collected…

Structural Monotonicity in Transmission Scheduling for Remote State Estimation with Hidden Channel Mode

Hampei Sasahara

This study treats transmission scheduling for remote state estimation over unreliable channels with a hidden mode. A local Kalman estimator selects scheduling actions, such as powe…

Data Informativity for Quadratic Stabilization under Data Perturbation

Taira Kaminaga, Hampei Sasahara

Assessing data informativity, determining whether the measured data contains sufficient information for a specific control objective, is a fundamental challenge in data-driven cont…
