Résumé

An innovative control strategy addressing the complexities of discrete interconnected nonlinear Hammerstein subsystems is presented. The approach combines decentralized sliding mode control (DSMC) with an event-triggered mechanism (ETM) to efficiently manage complex systems characterized by discrete elements, nonlinear behavior, and interconnections. The event-triggered sliding mode control (ETSMC) framework offers a distributed control solution that utilizes the robustness and disturbance tolerance of sliding mode control while optimizing resource usage and network communication through an event-triggered mechanism. A comprehensive analysis of stability and robustness ensures that the proposed control strategy stabilizes the system and achieves its design objectives, even in the presence of uncertainties or disturbances. The effectiveness of the approach is demonstrated through two simulation examples.
