Performance and implementability comparison of event-sampling based control schemes

In the last years, several works have been presented that address the study of the stability, analysis and control design suitable for event-based control schemes. Those advances have driven an impulse to the application of these control strategies in real environments, allowing a control-action rate reduction, while system stability is ensured and performance specifications are met. In this work, the study of three different event-based control schemes is presented, with the aim of comparing obtained performances, design processes and the implementability in real world applications. This work evaluates the behavioural characteristics of the control schemes: control rate and mean sampling time, system error and sensitivity to small disturbances. In addition, the study includes the sticking problem and the issues related to the implementability of the different schemes considered.
