Distributed Optimal Control over Graphs

Back
Abstract:
It has been known for a while that for linear systems interconnected over a graph, the problem of distributed and optimal linear quadratic controller design can be posed as a convex problem, under the condition that the distributed controller structure is the same as the graph structure. In spite of the nice convexity results, the problem is infinite-dimensional, and a practical solution has been out of reach. In this talk, we will introduce a novel approach to attack the problem, where we show how to find state-space solutions based on (finite-dimensional) Riccati equations.
