摘要: 针对网络环境下控制系统的协同设计问题展开研究. 首先应用工业网络特性建立了依赖于网络参数和控制参数的网络服务质量模型, 并且在此基础上分析了网络性能与控制性能的强耦合关系. 进而, 提出给定控制系统性能指标和网络资源受限条件下的控制参数和网络参数的联合优化设计方法. 最后通过实验证明本文方法的有效性.Abstract: 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.
