This　paper　investigates　the　mean　square　bipartite　consensus　problem　of　a　multi-agent　system　with　considering　measurement　noises　and　communication　time-delays.　And　the　interaction　topology　of　the　multi-agent　system　(MAS)　is　a　signed　digraph.　The　convergence　of　the　proposed　bipartite　consensus　protocol　with　both　noisy　measurements　and　uniform　communication　time-delays　is　analyzed.　Sufficient　conditions　on　the　upper　bound　of　the　time-delays　are　first　derived　to　guarantee　the　mean　square　bipartite　consensus　for　the　signed　digraph　which　is　structurally　balanced　and　has　a　spanning　tree.　Then　for　the　signed　digraph　which　is　structurally　unbalanced　and　strongly　connected,　the　states　of　all　agents　achieve　zero　in　the　mean　square　sense　under　the　given　conditions.　Finally,　numerical　simulation　examples　are　provided　to　illustrate　the　obtained　theoretical　results.　©　2021,　ICROS,　KIEE　and　Springer.
