Abstract：When suffering from the denial of service(DoS)attacks,the resilient control problem of distributed train control systems has attracted widespread attention.In this paper,a resilient control strategy based on the distributed state observer of the leader train and the barrier Lyapunov function is proposed,which can not only avoid train collisions,but also achieve the platoon control objective.Firstly,under DoS attacks,a distributed state observer of the leader train is proposed to estimate the states of the leader train in real time.Theoretical analysis shows that the estimated error of the state observer is exponentially stable on the condition that the DoS attack satisfies certain constraints.On this basis,by transforming the train collision avoidance problem into a state-constrained problem,a state-constrained control law based on the barrier Lyapunov function is proposed,which solves the resilient platoon control problem,to ensure collision avoidance under DoS attacks.Finally,numerical simulation confirms the effectiveness of the proposed method.
