In　this　paper,　we　study　stability　and　L1-gain　problems　for　switched　positive　systems,　in　which　stability　for　any　subsystems　do　not　necessarily　requirement.　First,　the　sufficient　condition　for　exponential　stability　is　established.　By　exploiting　the　multiple　linear　co-positive　Lyapunov　function　method,　stabilization　and　L1-gain　conditions　of　switched　positive　systems　are　proposed.　To　reduce　the　switching　frequency,　a　mixed　switching　strategy　is　proposed,　which　is　different　from　traditional　state-dependent　or　time-dependent　switching.　Then,　a　set　of　state-feedback　controllers　and　a　mixed　switching　strategy　are　dual　developed　to　stabilize　the　system,　and　the　corresponding　linear　vector　inequalities　are　examined　in　terms　of　linear　programming.　Furthermore,　L1-gain　is　studied　as　well.　Finally,　a　numerical　example　is　provided　to　show　the　validity　of　the　proposed　techniques.　©　2020　Technical　Committee　on　Control　Theory,　Chinese　Association　of　Automation.
