Abstract: A modeling method for multi-packet transmission networked control systems(NCSs) with short delay is presented.The NCS is modelled as models of linear switched control systems under certain switching sequences.With switched control system theory and robust stability theory,the sufficient conditions for the asymptotic stability criterion of NCS with multi-packet transmission are obtained,and the method to design a periodically dynamic output feedback stabilization controller is firstly put forward in this paper.Numerical examples demonstrate the conclusions are feasible and effective.
