This　study　handles　the　issues　of　stability　and　guaranteed　cost　for　switched　positive　systems　based　on　a　novel　multiple　linear　copositive　Lyapunov　functions　approach.　Two　different　switching　policies　are　devised.　The　first　one　relies　on　continuous　time　strategy　and　the　other　depends　on　the　sampled-data　strategy.　The　designed　switching　policies　not　only　render　the　considered　systems　globally　exponentially　stable　with　a　pre-specified　adequate　level　of　performance,　but　also　decrease　the　switching　frequency　to　rule　out　the　Zeno　behaviour.　New　stability　conditions　are　presented　in　form　of　linear　vector　equality　as　well　as　linear　vector　inequalities,　which　can　be　readily　solved　by　employing　Linprog　function.　Moreover,　based　on　the　attained　stability　results,　the　authors　further　research　an　infinite　time　cost　function.　The　effectiveness　of　the　proposed　methods　is　validated　and　illustrated　via　simulation　results.　©　The　Institution　of　Engineering　and　Technology　2019.
