Abstract: In this talk, we consider seeking (generalized) Nash equilibrium (GNE) over networks for noncooperative games. We reveal the convergence of a typical gradient-play dynamics for GNE seeking from a passivity-based perspective, and then, propose two novel dynamics by passivity-based modification on the gradient-play scheme with convergence guarantees in merely monotone regimes. Following that, resorting to passivity, we develop a unifying framework to generalize the gradient-play dynamics. In addition, we consider a noncooperative game problem played by nonlinear agents with uncertainty. We establish a two-layer framework and systematically convert this problem into a distributed output regulation problem. Under some standard assumptions, we design control laws such that outputs of agents to reach the Nash equilibrium of the game.
