Multi-Objective Linear Quadratic Team Optimization
Ather Gattami
In this paper, we consider linear quadratic team problems with an arbitrary number of quadratic constraints in both stochastic and deterministic settings. The team consists of play…
Deterministic Team Problems with Signaling Incentive
Ather Gattami
This paper considers linear quadratic team decision problems where the players in the team affect each other's information structure through their decisions. Whereas the stochastic…
Iterative Source-Channel Coding Approach to Witsenhausen's Counterexample
Johannes Kron, Ather Gattami, Tobias J. Oechtering +1
In 1968, Witsenhausen introduced his famous counterexample where he showed that even in the simple linear quadratic static team decision problem, complex nonlinear decisions could…
Optimal Control and Estimation for Partially Nested Interconnected Systems
Ather Gattami, Sanjoy Mitter
In this paper, we study distributed estimation and control problems over graphs under partially nested information patterns. We show a duality result that is very similar to the cl…
On Optimal Distributed Output-Feedback Control over Acyclic Graphs
Ather Gattami, Omid Khorsand
In this paper, we consider the problem of distributed optimal control of linear dynamical systems with a quadratic cost criterion. We study the case of output feedback control for…
Optimal Distributed Controller Synthesis for Chain Structures: Applications to Vehicle Formations
Omid Khorsand, Assad Alam, Ather Gattami
We consider optimal distributed controller synthesis for an interconnected system subject to communication constraints, in linear quadratic settings. Motivated by the problem of fi…
