Impacts of Wireless Channels in System Control

Abstract

Conventional wireless communications have been developed aiming higher frequency efficiency, or higher speed, for a given bandwidth with acceptable average error rate. In many wireless controls, on the contrary, data to be sent is relatively small and high data rate is not required, however, the data has to arrive to its destination just-in-time with high reliability. Based on these differences, this presentation introduces the recent works on impacts of wireless technology for control systems, measure of reliability, and strategies for performance improvements.
