| 摘 要： | 针对网络控制系统中网络带宽受限所产生的传输延时问题提出一种基于混杂系统技术的建模方法,采用动态输出反馈形式给出了闭环网络控制系统描述,将采样周期和传输延时为常数的情况推广到时变情况,使所建立的模型更具有一般性;并运用混杂系统理论分析了网络控制系统的稳定性,避免了将其转化成一般延时系统构造Lyapunov函数所带来的困难.增大系统稳定域的同时,使系统具有良好的动态性能.仿真结果说明了此方法的可行性和有效性.

| Abstract: | A modeling method based on hybrid system technology for a class of networked control systems with network induced delay is presented. The stability of networked control systems is analyzed using the theory of hybrid systems. A stabilizing dynamic output feedback controller is designed to implement the stability of the closed-loop system to avoid the difficulty caused by constructing Lyapunov functions of time delay systems. The condition on which the sampling period and transmission delay become constant is extended to be a time variant condition with the system model generalized. The stability region is thus enlarged with satisfactory dynamic performance. Simulation results show the feasibility and efficiency of the proposed method. |
