Leader-following consensus under disturbances is solved by modeling it as a coalitional zero-sum game that yields an H∞ law implementable distributively through GARE decomposition and dynamic average consensus.
An online algorithm for zero-sum LQ games with unknown dynamics combines model estimation and surrogate selection to achieve regret bounds on policy convergence.
