Abstract

In this paper the development and experimental verification of a mobile client-centric networked controlled system is presented. The feedback control loop is closed over a general purpose radio service (GPRS) communication channel, between the plant (server) and the controller (client). The client-centric nature dictates that the client initiates all the data transmissions. The inserted delays from the communication network are time-varying and degrade the system dynamic performance, while forcing the system to instabilities. The designed controller has primitive characteristics and ensures the stability of the overall discrete time-delayed system. Linear matrix inequality theory based theoretical results provide the worst-case scenario of the latency time that this controller can tolerate.
