Disturbance Attenuation Bounds in the Presence of a Remote Preview

Abstract

We study the fundamental limits of disturbance attenuation of a networked control scheme, where a remote preview of the disturbance is available. The preview information is conveyed to the controller, via an encoder and a finite capacity channel. In this article, we present an example where we design a remote preview system by means of an additive, white and Gaussian channel. The example is followed by a summary of our recent results on general performance bounds, which we use to prove optimality of the design method.
