Strategic Monitoring of Networked Systems with Heterogeneous Security Levels
Jezdimir Milosevic, Mathieu Dahan, Saurabh Amin +1
We consider a strategic network monitoring problem involving the operator of a networked system and an attacker. The operator aims to randomize the placement of multiple protected…
Attack Impact Evaluation for Stochastic Control Systems through Alarm Flag State Augmentation
Hampei Sasahara, Takashi Tanaka, Henrik Sandberg
This note addresses the problem of evaluating the impact of an attack on discrete-time nonlinear stochastic control systems. The problem is formulated as an optimal control problem…
How are policy gradient methods affected by the limits of control?
Ingvar Ziemann, Anastasios Tsiamis, Henrik Sandberg +1
We study stochastic policy gradient methods from the perspective of control-theoretic limitations. Our main result is that ill-conditioned linear systems in the sense of Doyle inev…
Scale Fragilities in Localized Consensus Dynamics
Emma Tegling, Bassam Bamieh, Henrik Sandberg
We consider distributed consensus in networks where the agents have integrator dynamics of order two or higher (). We assume all feedback to be localized in the sense that…
On Uninformative Optimal Policies in Adaptive LQR with Unknown B-Matrix
Ingvar Ziemann, Henrik Sandberg
This paper presents local asymptotic minimax regret lower bounds for adaptive Linear Quadratic Regulators (LQR). We consider affinely parametrized -matrices and known -matric…
A secure state estimation algorithm for nonlinear systems under sensor attacks
Michelle S. Chong, Henrik Sandberg, Joao P. Hespanha
The state estimation of continuous-time nonlinear systems in which a subset of sensor outputs can be maliciously controlled through injecting a potentially unbounded additive signa…
