Optimal Infinite-Horizon Mixed Control
Vikrant Malik, Taylan Kargin, Joudi Hajar +1
We study the problem of mixed control in the infinite-horizon setting. We identify the optimal causal controller that minimizes the …
The Distributionally Robust Infinite-Horizon LQR
Joudi Hajar, Taylan Kargin, Vikrant Malik +1
We explore the infinite-horizon Distributionally Robust (DR) linear-quadratic control. While the probability distribution of disturbances is unknown and potentially correlated over…
Distributionally Robust Kalman Filtering over Finite and Infinite Horizon
Taylan Kargin, Joudi Hajar, Vikrant Malik +1
This paper investigates the distributionally robust filtering of signals generated by state-space models driven by exogenous disturbances with noisy observations in finite and infi…
Regret-Optimal Defense Against Stealthy Adversaries: A System Level Approach
Hiroyasu Tsukamoto, Joudi Hajar, Soon-Jo Chung +1
Modern control designs in robotics, aerospace, and cyber-physical systems rely heavily on real-world data obtained through system outputs. However, these outputs can be compromised…
Robust Optimal Network Topology Switching for Zero Dynamics Attacks
Hiroyasu Tsukamoto, Joshua D. Ibrahim, Joudi Hajar +3
The intrinsic, sampling, and enforced zero dynamics attacks (ZDAs) are among the most detrimental stealthy attacks in robotics, aerospace, and cyber-physical systems. They exploit…
Infinite-Horizon Distributionally Robust Regret-Optimal Control
Taylan Kargin, Joudi Hajar, Vikrant Malik +1
We study the infinite-horizon distributionally robust (DR) control of linear systems with quadratic costs, where disturbances have unknown, possibly time-correlated distribution wi…
