摘要
提出一种短时延多包传输网络控制系统的建模方法.把多包传输网络控制系统建模为具有一定切换规则的线性切换系统模型.利用切换系统理论和鲁棒稳定性理论,得到多包传输网络控制系统的渐近稳定性判据,并首次提出周期动态输出反馈镇定控制器的设计方法.最后通过数值算例证明文中结论的可行性和有效性.
A modeling method for multi-packet transmission networked control systems （NCSs） with short delay is presented. The NCS is modelled as models of linear switched control systems under certain switching sequences. With switched control system theory and robust stability theory, the sufficient conditions for the asymptotic stability criterion of NCS with multi-packet transmission are obtained, and the method to design a periodically dynamic output feedback stabilization controller is firstly put forward in this paper. Numerical examples demonstrate the conclusions are feasible and effective.
