针对存在介质访问约束的网络化控制系统,研究其中的控制和通信协同设计问题.将网络化控制系统建模为输入矩阵随介质约束而变化的切换系统,运用最优控制理论和切换系统分析方法,设计了可动态调度的最优控制器及实时切换规则,并分析了动态调度下闭环网络化控制系统的稳定性,最后通过仿真验证了该方法的有效性.
The control and communication co-design for networked control systems with medium access constraints is discussed.A networked control system is modeled as a switched system whose input matrixes vary with medium access constraints.Based on the analytical methods of switched systems and optimal control theory,a dynamic scheduling optimal controller and the corresponding real-time switch rules are proposed.The stability of the closed-loop networked control system under dynamic scheduling is also analyzed.A simulation is given to illustrate the effectiveness of the proposed method.
