In a platoon control system, a fixed and symmetrical topology is quite rare, because of adverse communication environments and continuously moving vehicles. This paper presents a DASMC (Distributed Adaptive Sliding Mode Control) scheme for more realistic vehicular platooning. In this scheme, adaptive mechanism is adopted to handle platoon parametric uncertainties, while a structural decomposition coupling of interaction topology. mA enthuomde rdiceaall sa wlgiothri ththme based on LMI (Linear Matrix Inequality) is developed to r pelaqcueir etdh ea rpeoa letos boafl atnhcee sqluidicinkgn emsso taionnd sdmynoaomthincse ssin.
