| 摘 要： | 在网络控制系统中，网络负载的加重会使网络资源变得有限，从而使各个子系统的控制性能变差．为了改善这一情况下系统的控制品质（quality of control, QoC），本文提出了流动式死区反馈调度方法．通过对死区节点的动态选择和对死区范围的连续分配，整个系统在网络资源有限的情况下总的控制品质得到了提高．仿真结果表明，在网络资源紧缺时，该方法采用的流动式死区思想和死区范围连续化思想对系统QoC的提高是有效的．

| Abstract: | With the network workload increasing,the network resource will be limited and control performance of the subsystems in the networked control system(NCS)will be worsened.In order to improve the system quality of control (QoC)in this situation,a floating deadband feedback scheduling approach is proposed.Through dynamic selection of the deadband node and continuous assignment of the deadband range,QoC of the overall systems is enhanced with the limited network resource.Simulation results show that the ideas of... |
