Abstract

Advances in networked control systems have created new opportunities and challenges in controlling large-scale systems composed of several interacting subsystems. Many researchers have considered the problem of distributed control of such systems. However, at the heart of these control methods lies the (sometimes implicit) assumption that the designer has access to the global plant model information when designing a local controller. In contrast, in this talk we formulate and solve some distributed control design problems where the full plant model is not globally available. We investigate the achievable closed-loop performance of linear plants under a quadratic cost performance and give some fundamental bounds. We motivate and illustrate the results through applications in transportation and power systems.
