On characterizing the interaction between dynamical behavior and information flow in networked control

In control design framework, the analysis on the stability and observability of a dynamic system is usually realized in the first place, and the quantity and quality of information exchanging is then considered in the second place. However, the interaction between information flow and system dynamics should be treated equally in real-world control applications. In this paper, the interaction lying between information constraint and dynamic behavior of a system is characterized. A framework with information flow and plant is proposed and related mathematical foundations are presented. In the end, three case studies: on-line interactive 3D video game, ball-camera system, and the location prediction of moving objects are shown.
