Passivity techniques have been recently used to solve stabilization prob- lem of multi-agent systems . For instance, the interpretation of an opti- mization-based network flow control as a closed-loop system and the use of passivity can be used to prove the stability of a class ofthe system passive is also designed. Keywords: Switched systems ; Passivity ; Stability 1 Introduction The passivity concept was introduced by Willems and developed further by Hill and Moylan . Passivity of non- linear systems has attracted great interest in the control area
