Title
Optimal Local and Remote Controllers with Unreliable Uplink Channels.
Abstract
We consider a networked control system consisting of a remote controller and a collection of linear plants, each associated with a local controller. Each local controller directly observes the state of its colocated plant and can inform the remote controller of the plantu0027s state through an unreliable uplink channel. We assume that the downlink channels from the remote controller to local controllers are perfect. The objective of the local controllers and the remote controller is to cooperatively minimize a quadratic performance cost. We provide a dynamic program for this decentralized control problem using the common information approach. Although our problem is not a partially nested problem, we obtain explicit optimal strategies for all controllers. In the optimal strategies, all controllers compute common estimates of the states of the plants based on the common information obtained from the communication network. The remote controlleru0027s action is linear in the common state estimates, and the action of each local controller is linear in both the actual state of its colocated plant and the common state estimates. We illustrate our results with numerical experiments using randomly generated models.
