Rate-cost Trade-offs in H-infinity Control with Initial State Uncertainty
Vikrant Malik, Victoria Kostina, Babak Hassibi
We consider the problem of H-infinity control in the presence of a digital communication channel between the observer and the controller and investigate the fundamental trade-off b…
Deriving Approximate Message Passing from the Convex Gaussian Min-Max Theorem
Vikrant Malik, Babak Hassibi
Approximate message passing (AMP) provides fast iterative algorithms for high-dimensional signal recovery with Gaussian design matrices, while the Convex Gaussian Min--max Theorem…
Quantized Online LQR
Barron Han, Victoria Kostina, Babak Hassibi
We study online linear-quadratic regulation (LQR) with unknown dynamics under communication rate constraints. Classical networked control quantizes the plant state at every time st…
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…
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…
Coded Kalman Filtering over MIMO Gaussian Channels with Feedback
Barron Han, Oron Sabag, Victoria Kostina +1
We consider the problem of remotely stabilizing a dynamical system. A sensor (encoder) co-located with the system communicates with a controller (decoder), whose goal is to stabili…
A Distributionally Robust Approach to Shannon Limits using the Wasserstein Distance
Vikrant Malik, Taylan Kargin, Victoria Kostina +1
We consider the rate-distortion function for lossy source compression, as well as the channel capacity for error correction, through the lens of distributional robustness. We assum…
