  • 摘要: 对于通信约束的网络控制系统,应用通信序列的概念和混合逻辑动态的构架,将其建模成一类集成控制和调度的资源约束离散线性周期系统.给出了这类系统网络信息的可调度条件,并基于线性矩阵不等式设计动态反馈控制律.仿真表明,该方法能够在网络信息的周期调度下使闭环系统渐近稳定.

     

    Abstract: 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.
