contents This paper addresses a class of Nash equilibrium (NE) seeking problems in coalition games involving both local and coupling constraints for multiple Euler-Lagrange (EL) systems subject to disturbances of unknown bounds. Within each coalition, agents cooperatively minimize a shared cost function while competing against other coalitions. A distributed strategy is proposed to seek the NE under informational constraints, where each agent has access only to its own action, cost function, and constraint parameters. In the proposed distributed NE seeking strategy, adaptive techniques are combined with sign functions to handle model uncertainties and disturbances with unknown bounds in the EL systems. To deal with the Lagrange multipliers associated with local and coupling constraints, primal-dual techniques are integrated with consensus protocols. Additionally, a dynamic average consensus algorithm is employed to estimate the gradient of the coalition cost function, while a leader-following protocol is utilized to estimate the actions of other agents. Under standard convexity and graph-connectivity assumptions, global convergence of the closed-loop EL system to the NE is established. As an illustrative application, a swarm confrontation of unmanned surface vehicles involving formation, encirclement, and interception tasks is modeled within the coalition game framework, and numerical simulations are conducted under this model to validate the theoretical results.
