Abstract
En 中文
This paper investigates the problem of globally fixed-time longitudinal cooperative control for intelligent connected vehicle platoons (ICVPs) subjected to denial-of-service (DoS) attacks. First, a novel distributed fixed-time observer is designed to estimate the state information of the leading vehicle under DoS attacks. Subsequently, by leveraging the switching system framework and fixed-time stability theory, we guarantee that the estimation error converges to zero within a fixed time. On this basis, a distributed fixed-time controller based on integral sliding mode strategy is designed, which can stabilize the vehicle tracking error system within a fixed time and maintain a safe inter-vehicle distance. Finally, the effectiveness of the proposed control method is verified through simulation and comparative experiments.
