Output-based event-triggered control systems under Denial-of-Service attacks

Abstract

In this paper, we propose a dynamic event-triggered control (ETC) strategy for output-based feedback systems in the presence of Denial-of-Service (DoS) attacks. These malicious DoS attacks aim to impede the communication of measurement data in order to endanger the functionality of the closed-loop system. We show that the proposed ETC scheme, if well designed, can tolerate a class of DoS signals characterized by frequency and duration properties without jeopardizing the stability, performance and Zeno-freeness of the ETC system.
