We all know for a control system, the quality of information (e.g. state info, context info) could have significant impacts on control performance like stability and convergence rate, etc. To theoretically explore such impacts, it is important to adopt suitable system model and corresponding theory. for example, multi-agent system and theory to model coordination control problems and analyze the impact of information flow. In context of cloud computing and IoT more information could be available for a typical control system like traffic control, I just wonder what popular theory framework can apply to such applications? Is there any related surveys to read? thanks a lot.
