Event-based output-feedback control

Event-based control aims at reducing the information exchange over the communication network in control systems. This paper extends an event-based state-feedback approach published recently towards event-based output feed back. The measurable output is affected by measurement noise. The analysis shows that by incorporating a state observer in the event generator, a stable behavior of the event-based control loop can be guaranteed. Moreover, it will be shown that the maximum communication frequency within the control loop is bounded.
