Co-design Methodology for Network-based Control Systems Based on QoS
基于网络QoS的控制系统协同设计方法研究

The co-design method of networked control systems (NCS) is studied in this paper. First, a networked quality of service (QoS) model dependent on both controlling and communication parameters is established by using the industrial network characteristics. Furthermore, based on this, the strong coupling relation between the network performance and the control performance is analyzed. Then, under the given control performance and network resource-constrained conditions, an optimal co-design method for determining the control and communication parameters is proposed in detail. Finally, the experimental results show the validity of the proposed method.
