Data-Driven Asynchronous Event-Triggered Control for Discrete-Time Switched Linear Systems Subject to Disturbances

This paper investigates the data-driven event-triggered control problem for discrete-time switched linear systems subject to external disturbances and event-induced asynchronous switching behavior. First, a novel data representation of the system is established to facilitate the design of the event-triggered controllers. Subsequently, under a merging average dwell time switching signal, the data-dependent controller gains and derive sufficient conditions are concurrently synthesized to guarantee the practical exponential stabilization of the closed-loop system. Furthermore, the disturbance-free scenario is directly obtained as a special case. In contrast to existing model-driven results, the proposed approach relies solely on collected data, thereby significantly enhancing its practical applicability. Finally, a numerical example is provided to validate the effectiveness of the findings.
