Event‐based dynamic output feedback control of fuzzy systems against DoS attacks

Abstract

This paper deals with the event‐triggered dynamic output feedback control for fuzzy systems against denial‐of‐service (DoS) attacks. The DoS attack behavior is modeled using a binary Markov chain to reflect the unreliability of the communication channel. To reduce network communication overhead, a novel probabilistic event‐triggered protocol with uncertain probabilities is introduced. Additionally, the potential mismatches between premise variables and modes in both the fuzzy system and the controller are accounted, leading to the design of a dual‐asynchronous dynamic output feedback controller. Finally, the efficacy of the proposed approach is validated through a comprehensive numerical example, highlighting its effectiveness in handling asynchronous control scenarios and DoS attack resilience in fuzzy systems.
