This　paper　investigates　an　H∞　intermittent　control　strategy　for　multi-area　power　system　(PS).　Firstly,　the　model　of　multi-area　PS　with　disturbance　is　constructed.　Then,　according　to　the　characteristics　of　intermittent　control,　a　suitable　Lyapunov　function　is　selected　and　a　design　method　of　intermittent　control　is　proposed　by　using　linear　matrix　inequalities　(LMIs)　to　guarantee　the　exponential　stability　and　L2-gain　performance.　Finally,　the　H∞　intermittent　control　is　proved　effective　by　taking　a　3-area　PS　as　an　example.　©　2022　IEEE.
