Abstract This paper focuses on the event-triggered consensus tracking of high-speed trains under denial-of-service (DoS) attacks. A novel anti-disturbance control strategy is proposed, based an adaptive memory state observer and a disturbance observer. introduced to buffer system output information which enhancing precision observer, gust during train operation estimated by The Linear Matrix inequality technique used obtain feedback coefficient controller gain, Lyapunov theory employed demonstrate controller’s consistency performance. Applying mechanism, new scheme designed better ensure performance effectively prevent occurrence Zeno behavior. To achieve precise identification DoS attacks in environment, detection algorithm proposed. Finally, simulation examples are validate effectiveness practicality proposed scheme.
