Finite-time control for cross-domain systems tracking a non-cooperative target under DoS attacks

The challenges faced by practical cross-domain systems tracking a non-cooperative target can be classified into two main aspects: difficulty in acquiring target dynamics and vulnerability to denial-of-service (DoS) attacks. To tackle the former challenge, which refers to the non-cooperative target problem, this study establishes a network weight model to represent the dynamics of the non-cooperative target. This model enables tracking of the target without relying on direct target dynamics, eliminating the requirement for target system matrix estimation. Regarding the latter challenge, which typically causes topology switching, a straightforward solution is to ensure the successful operation of the cross-domain robot system even under switching topologies. Hence, building upon the established non-cooperative target network model, this paper presents a distributed cross-domain system control method that is capable of adapting to scenarios involving DoS attacks. The proposed method is validated to be effective through simulations, with convergence times of 10 s and 90 s in numerical and physical simulations, respectively, within the simulation environment designed in this paper.
