| 摘 要： | 针对一类通信受限的网络控制系统,研究量化反馈控制器及动态调度策略的联合设计问题.考虑到介质访问约束和信号量化误差的影响,将网络控制系统建模为等价的离散时间切换系统;通过Lyapunov稳定理论推导出保证系统鲁棒稳定的模式及量化依赖型充分条件,并给出了量化反馈控制器的设计方法;在此基础上,设计了基于实时状态的动态通信调度策略,实现了网络控制系统的镇定控制.最后通过仿真示例验证了所提出方法的有效性.

| Abstract: | This paper is concerned with the joint design of quantized feedback control and dynamic scheduling for networked control systems with constrained communication capacity. A new discrete-time switched system is proposed to the networked control system subject to both communication constraints and input quantization. By using Lyapunov stability theory, sufficient conditions of mode and quantization-dependent robust stabilization and a quantized feedback controller are derived for networked control system. Based on the model of switched system, a dynamic scheduling policy is designed to guarantee the asymptotic stability of close-loop system. An illustrative example is finally given to show the effectiveness of the proposed method. |
