An approach to event-triggered control of unstable dissipative systems exemplified via PI controller

The recent advent of “smart” technologies in the industry has increased the interest on techniques able to lighten the burden on communication networks. In this framework, the debate on event triggered controllers has been heated by many recent and promising developments from a number of different approaches. In this paper we investigate the potential of an original input-output event triggering strategy via an ideal implementation. Special attention is put on the worst case scenario, where systems in the control loop are not stable in free running configuration. A detailed numerical example featuring a Proportional-Integral controller is then used to test the obtained performance against a common technique.
