This　paper　investigates　the　fixed-time　leader-following　consensus　tracking　problem　for　multiple　wheeled　mobile　robots　in　the　presence　of　external　disturbances,　where　both　the　dynamics　and　kinematics　levels　of　multi-robot　systems　are　taken　into　account.　A　novel　fixed-time　distributed　estimator-controller　scheme　is　proposed　to　achieve　the　consensus　tracking　within　a　fixed　time　independent　of　initial　conditions.　Based　on　Lyapunov　stability　method　and　H∞　theory,　sufficient　conditions　and　the　upper　bound　of　settling　time　for　the　closed-loop　system　are　obtained,　and　the　L2　gain　of　the　system　is　equal　to　or　less　than　γ　that　shows　strong　robustness　to　the　disturbances.　Finally,　the　simulation　results　are　given　to　show　the　feasibility　and　effectiveness　of　the　designed　control　method.　©　2024　IEEE.
