We propose and partially analyze a new model for determining the
influence of a controller's interconnection graph on closed-loop
performance in distributed control design problems. Given a plant
composed of dynamically uncoupled subsystems, we investigate the
existence and properties of an optimally structured controller, when
one of the weight matrices of a classical LQR cost function is
topology-dependent. We also give some theoretical results as to the
existence of "critical prices" at which adding supplementary edges
becomes deterimental to closed-loop performance.
