Abstract [en]

This paper develops a controller synthesis method for distributed LQG controlproblems under output-feedback. We consider a system consisting of three interconnected linearsubsystems with a delayed information sharing structure. While the state-feedback case haspreviously been solved, the extension to output-feedback is nontrivial as the classical separationprinciple fails. To nd the optimal solution, the controller is decomposed into two independentcomponents: a centralized LQG-optimal controller under delayed state observations, and a sumof correction terms based on additional local information available to decision makers. Explicitdiscrete-time equations are derived whose solutions are the gains of the optimal controller.
