In　this　paper,　we　study　the　cooperative　semi-global　robust　output　regulation　problem　for　a　class　of　minimum　phase　nonlinear　uncertain　multi-agent　systems.　This　problem　is　a　generalization　of　the　leader-following　tracking　problem　in　the　sense　that　it　further　addresses　such　issues　as　disturbance　rejection,　robustness　with　respect　to　parameter　uncertainties.　To　solve　this　problem,　we　first　introduce　a　type　of　distributed　internal　model　that　converts　the　cooperative　semi-global　robust　output　regulation　problem　into　a　cooperative　semi-global　robust　stabilization　problem　of　the　so-called　augmented　system.　We　then　solve　the　semi-global　stabilization　problem　via　distributed　dynamic　output　control　law　by　utilizing　and　combining　a　block　semi-global　backstepping　technique,　a　simultaneous　high　gain　feedback　control　technique,　and　a　distributed　high　gain　observer　technique.　(C)　2014　Elsevier　Ltd.　All　rights　reserved.
