Abstract :
This paper addresses the control of spatially distributed processes over a network that imposes bandwidth constraints and communication delays. Optimal communication policies are derived for an estimator-based networked control system architecture to reduce the communication load. These policies arise as solutions of an average cost optimization problem, which is solved using dynamic programming. The optimal policies are shown to be deterministic.
