This paper studies networked control systems closed over digital erasure channels, when a class of source coding schemes is employed. Building upon recent results, we show that it is possible to convert analysis and design problems involving digital erasure channels into problems involving two signal-to-noise ratio (SNR) constrained channels in series, one subject to an equality SNR constraint, and the second one subject to an inequality SNR constraint. This insight is then used to establish a sufficient condition on the channel average data-rate and dropout probability that allow one to achievemean square stability.We also provide performance guarantees and a numerical example to illustrate our results. © 2011 IFAC.
