This　paper　considers　a　bumpless　transfer　control　design　problem　to　guarantee　the　asymptotic　stability　with　safety　performance　for　switched　systems.　Firstly,　for　a　switched　system,　the　safety　condition　which　is　expressed　as　a　common　control　barrier　function　(CCBF)　is　unified　with　the　asymptotic　stability　condition　which　is　expressed　as　a　set　of　safety-based　multiple　control　Lyapunov　functions　(SMCLFs)　in　the　context　of　real-time　optimization　based　controllers.　Then,　based　on　an　average　dwell　time　approach,　the　bumpless　transfer　controller　is　designed　through　constructing　a　CCBF　and　SMCLFs　in　the　context　of　a　quadratic　program　(QP).　Finally,　the　mediation　of　the　safety　performance　and　the　asymptotic　stability　performance　through　a　QP　is　demonstrated　on　two　examples.　©　2024　Technical　Committee　on　Control　Theory,　Chinese　Association　of　Automation.
