| Abstract: | 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. |
