For　flexible　spacecraft　under　disturbances　and　deception　attacks　which　makes　the　aircraft　unable　to　operate　according　to　the　predetermined　attitude　or　trajectory,　this　paper　addresses　H∞　fault-tolerant　control　strategy.　Firstly,　the　flexible　spacecraft　attitude　control　model　and　structure　of　fault-tolerant　controller　with　deception　attacks　is　constructed.　Secondly,　the　control　law　derived　by　linear　matrix　inequality　(LMI)　is　obtained　by　using　the　Lyapunov　function　and　H∞　control　theory.　In　the　last　of　this　paper,　the　validity　of　design　method　is　verified.　©　2023　IEEE.
