Event-triggered Formation Control of Underactuated USVs under DoS Attacks
A distributed leader-follower formation control strategy with an event-triggered mechanism is proposed for underactuated unmanned surface vessels(USVs)under denial-of-service(DoS)attacks. To address communication failures in USV formations during DoS attacks,a distributed state observer is designed to estimate the virtual leader's state information. A novel error transformation method is introduced to circumvent the controller expression complexity of controller caused by the backstepping approaches,and the auxiliary variables are incorporated to resolve the control challenges induced by underactuation. Based on this framework,a unified controller structure is developed via event-triggered control to simultaneously achieve the formation trajectory tracking and stabilization. This eliminates the computational burdens and response delays caused by frequent controller switching. Theoretical analysis proves that the formation control errors converge to a bounded range near zero point,and the controller does not exhibit Zeno behavior. Finally,the effectiveness of the proposed method is validated by means of comparative simulations.
