Abstract
This paper considers the problem of containability for a scalar linear unstable system where the communication from the sensor to the actuator is performed over a network with finite capacity The possibilities of event-based sampling concepts in a setup with memoryless coding and decoding components acting together with a static controller are investigated. A robust controller is designed such that the finite communication control system employs an arbitrary possibly vanishing, average data rate in a delay free setup while guaranteeing containability The controller can be applied in the presence of delays as well, whereas the sampling mechanism needs to be adjusted. This leads to an increasing data rate and this increase is precisely quantified. Indications why the uncertainty in time rather than the pure delay causes the increasing data rate are given as well as considerations regarding the relation of transmitted bits and delay.
