Message Scheduling and Asymptotic Stability of System with Resource Constraints

By employing the notion of communication sequence and mixed logical dynamical framework,a networked control system(NCS) subject to communication constraints is modeled into a discrete-time linear period resource-constrained system in which control and scheduling are integrated.The schedulability conditions of this system are presented and a dy-namic feedback control law is also designed based on linear matrix inequalities(LMIs).Preliminary simulation results show that the proposed method can guarantee the asymptotic stability of closed loop systems under a certain periodic scheduling of network message.
