Experimental verification of aperiodic dynamic event-triggered control for linear systems using extended...

This paper presents an event-triggered control strategy that incorporates extended looped-functionals to enhance communication capacity efficiency in real-time systems. Among the various methods to guarantee stability in event-triggered mechanisms, this study focuses on a looped-functional approach and extends the conventional functionals to improve performance. Event-triggered control has been widely studied in various forms to improve communication efficiency and reduce computational load, and dynamic event-triggered control is often employed to prevent Zeno behavior and enhance performance. However, many of these studies have been analyzed only theoretically, with relatively few validated on actual hardware. To bridge the gap between theory and practice, this study experimentally verifies an advanced control topology that employs the extended looped-functional method with an aperiodic event-triggered technique. The conditions are derived as linear matrix inequalities to stabilize a linear system through aperiodic sampled-data control, and their effectiveness is demonstrated through numerical examples and experiments. The approach is experimentally validated on a rotary inverted pendulum system using the control gains obtained from the proposed conditions. Through this, it is intended to demonstrate that simulation-based studies can have a significant impact on real systems.
