Adaptive Event‐Triggered Mechanism for Uncertain Unmanned Surface Vehicle Systems Under Sequential Scaling Attacks

ABSTRACT

This investigation focuses on adaptive event triggered fault‐tolerant control for uncertain unmanned surface vehicle systems (UUSVs) in the bearing of actuator failures and sequential scaling attacks. In this model, the effects of actuator failures are addressed through the implementation of fault‐tolerant control strategies. As a result, an adaptive event‐triggered mechanism is proffered to reduce communication and computational overhead while ensuring system stability. In contrast to probabilistic models, a sequential scaling attack is taken into consideration, wherein certain attack characteristics, including attack frequency and duration, are specified. To guarantee stability, a comprehensive set of sufficient conditions has been established using Lyapunov stability theory within the context of linear matrix inequalities (LMIs). At the last, the effectiveness of put forward control scheme is demonstrated through a numerical example.
