This　study　concerns　the　fault-tolerant　boundary　consensus　control　design　problem　of　the　nonlinear　multiagent　systems　(MASs)　characterized　by　partial　differential　equations　(PDEs)　with　time-varying　delay　and　actuator　failures.　By　using　the　inequality　technique　and　Lyapunov　direct　method,　a　fault-tolerant　boundary　consensus　controller　design　is　developed　by　linear　matrix　inequalities　to　guarantee　that　the　nonlinear　delayed　consensus　error　systems　with　actuator　failures　are　exponentially　stable.　Finally,　a　MAS　modeled　by　PDEs　with　one　leader　and　four　followers　is　proposed　to　verify　the　feasibility　of　the　fault-tolerant　boundary　consensus　control　method　as　an　example.　©　The　Author(s),　under　exclusive　license　to　Springer　Nature　Singapore　Pte　Ltd.　2025.
