Observer Based Event-triggering Control of Unmanned Surface Vehicles under DoS Attacks

This paper is concerned with the stability analysis and controller design of observer-based unmanned surface vehicle under denial-of-service (DoS) attacks. Firstly, in order to save communication resources and resist DoS attacks, an observer-based event-triggering mechanism is proposed. Secondly, a new observer-based switched system model is established by using the time-delay system method. Based on this model, the expressions of observer and controller gain matrix are given by using the piecewise Lyapunov-Krasovskii functional approach and linear matrix inequalities (LMI) technique to ensure a certain control performance. Finally, simulations on an unmanned surface vehicle are given to verify the effectiveness of the design method proposed in this paper.
