A QSR-Dissipativity and Passivity based Analysis of Event-Triggered Networked Control Systems

In this paper, we show that dissipativity and passivity based control combined with event-triggered networked control systems (NCS) provide a powerful platform for designing cyber-physical systems (CPS). We propose QSR-dissipativity, passivity and finite-gain L-2-stability conditions for an event-triggered NCS in cases where an input-output event-triggering sampler condition is located on the plant's output side, controller's output side, or both sides leading to a considerable decrease in communication load amongst sub-units in NCS. We show that the passivity and stability conditions depend on passivity levels for the plant and controller. Our results also illustrate the trade-off among passivity levels, stable performance, and system's dependence on the rate of communication between the plant and controller.
