Abstract

Recently, there has been growing interest in stabilisability and performance problems in control over communication channels. Here we present an overview of recent results when a signal-to-noise ratio (SNR) constrained channel is considered. We discuss the linear time invariant (LTI) output feedback discrete-time case. Our analysis closely parallels results in bit rate limited control. The SNR framework used enables LTI stability, robustness, performance and delay analysis.
