This　work　exploits　a　state-dependent　switching　policy　to　deal　with　stability　analysis　and　L1-gain　performance　of　switched　positive　fuzzy　systems　with　time-delay.　By　dividing　up　the　nonnegative　state　space,　an　improved　state-dependent　switching　policy　is　devised.　The　main　advantages　of　the　proposed　switching　policy　are　that　the　chattering　behavior　commonly　arisen　in　traditional　state-dependent　switching　strategies　is　reduced　and　allows　each　subsystem　to　be　unstable.　Also,　sufficient　conditions　guaranteeing　asymptotic　stability　with　an　L1-gain　performance　are　derived　by　the　usage　of　multiple　linear　copositive　Lyapunov-Krasovskii　functionals　method.　Moreover,　the　proposed　approach　is　also　extended　to　cope　with　the　concerned　system　with　uncertainties,　in　particular　interval　ones.　Finally,　the　Lotka-Volterra　model　is　adopted　to　verify　the　validity　and　feasibility　of　the　conclusions.(c)　2022　Elsevier　B.V.　All　rights　reserved.
