Optimal Coordination of Homogeneous Agents Subject to Delayed Information Exchange

Madjidian, Daria LU ; Mirkin, Leonid and Rantzer, Anders LU (2014) 53rd IEEE Conference on Decision and Control
Abstract
We consider a class of large scale linear-quadratic coordination problems where the information exchange is subject to a time-delay. We show that several previously known properties of the optimal solution to the delay-free problem extend to this case. In particular, the optimal control law comprises a diagonal (decentralized) term complemented by a rank-one coordination term, which can be implemented by a simple averaging operation. Moreover, the computational effort required to obtain the controller is independent of the number of subsystems.
