This　paper　introduces　an　H　infinity　fault-tolerant　intermittent　load　frequency　control　(LFC)　strategy　for　multi-area　power　systems　(PS)　under　disturbances,　actuator　failures,　and　deception　attacks.　Initially,　in　order　to　reduce　the　required　cost　and　the　impact　caused　by　the　actuator　failures　in　the　multi-area　PS　under　disturbances　and　deception　attacks,　a　new　H　infinity　fault-tolerant　intermittent　control　scheme　is　proposed.　Subsequently,　by　developing　switching-time-dependent　Lyapunov　function,　the　exponential　stability　and　L2-gain　performance　are　guaranteed.　Finally,　the　H　infinity　fault-tolerant　intermittent　LFC　is　proved　effective　by　taking　a　three-area　PS　under　disturbances,　actuator　failures,　and　deception　attacks　as　an　example.
