This paper is concentrated on secure bipartite consensus problem of multiple Euler-Lagrange systems (MELSs) subject to denial-of-service (DoS) attacks. To overcome the difficulty of unavailability of leader information, the distributed observers are designed, under which the conservative assumption that each follower can access to leader is removed. Moreover, considering the problem that DoS attacks for communication between Euler-Lagrange systems can crash the system, several resilient controllers and observer gains are proposed to ensure the bipartite consensus of MELSs. Finally, numerical simulations are exhibited to verify the effectiveness of the theoretical results.
