In　this　article,　the　full　differential　privacy-preserving　problem　for　switched　LPV　systems　is　concerned.　The　security　of　a　control　system　is　the　ability　to　avoid　intentional　sabotage　or　accidental　interference　affecting　its　normal　operation.　For　switched　LPV　systems,　it　contains　both　internal　(scheduling　variable　and　switching　signal)　and　external　(system　output)　information　that　needs　to　be　protected,　we　adopt　differential　privacy　to　achieve　its　full　privacy　preserving.　The　resulting　challenges　are:　1)　privacy　design　for　three　types　of　system　signals　and　2)　dual　asynchronization　analysis　under　triple　privacy　noise.　Accordingly,　three　differential　privacy　definitions　and　Laplace　(resp.　uniform)　noise　design　methods　are　presented.　Sufficient　conditions　for　H∞　control　design　with　dual　asynchronization　analysis　are　given.　Finally,　simulation　results　verify　the　effectiveness　of　the　proposed　method.　©　2013　IEEE.
