Abstract: Based on communication sequence and considering the influence of uncertain short delay, this paper models the Networked Control System(NCS) with communication constraints as a discrete switching system with uncertainty, which integrates information scheduling and control. Based on the switching system theory and piecewise Lyapunov function method, the condition for asymptotic stability of system with periodical information scheduling is derived in the form of matrix inequalities, and a state feedback controller design method is provided. Simulation results validate the validity of this method.

摘要： 基于通信序列并考虑不确定短时延的影响，对具有通信约束的网络控制系统进行建模，使其成为参数不确定的集成信息调度与控制离散切换系统。基于切换系统理论和分段Lyapunov函数方法，以矩阵不等式形式给出在一定周期性信息调度策略下，使系统渐近稳定的条件，阐述状态反馈控制器的设计方法。仿真结果证明了该方法的有效性。
