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.
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 dynamic 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.
