摘　　要：针对一类具有通信约束的网络控制系统,采用Lyapunov-Metzler不等式方法研究动态调度协议和反馈控制器同步设计问题。动态调度协议根据系统的状态信息和使系统性能函数最小进行系统模态切换,从而将该调度策略下的网络控制系统建模为离散切换系统,结合切换系统理论给出了保证系统渐近稳定的动态调度策略和状态反馈控制器同步设计方法。最后通过仿真算例验证所提方法的有效性。The simultaneous design problem of dynamic scheduling and feedback control for networked control systems was investigated with time delay and communication constraints based on Lyapunov?Metzler inequalities method.Dynamic scheduling protocol,which makes the system performance function minimum based on the system state information,decides system switching mode.Networked control system under the scheduling strategy was modeled as a discrete switched system,combined with switching systems theory and LMI gives guarantee,the system gives asymptotically stable and dynamic scheduling policy,and state feedback controller was designed simultaneously.Finally,an illustrative example was given to demonstrate the effectiveness of the proposed method.
