In this lecture, we study the main issues with a packet-based control system and explore the frequently used models for such systems. In particular, we study the effect of packet drops and finite data rate on the system stability. We shall show that there are tradeoffs between packet drop rate, network data rate and system uncertainty levels for the closed loop system.
