| 摘 要： | 实现了基于simulink/Real-Time Workshop(RTW)的嵌入式网络化控制仿真系统，构建了以ARM7TDMI型cPu为核，运行uclinux操作系统的嵌入式平台。建立了广域网范围的网络环境，通过延时测量实验获得了网络延时统计特性，并针对该网络环境下的分布式控制系统的前向通道和反馈通道分别提出了延时补偿方法。同时系统还为用户提供了离线仿真，和通过网络在线指导现场控制的网络远程监控功能。最后以直流电机为被控对象，在广域网环境下进行了网络化控制系统实验，验证了该系统的有效性。 |

| Abstract: | Based on Simulink/Real-Time Workshop, the embedded networked control simulation system is realized. An embedded platform, which has ARM7TDMI as CPU core and uClinux as OS, is built. The statistic characteristics of network-induced time delay is obtained with time delay measured in WAN. The compensation methods for time delay in forward and feedback channels are presented. In addition, remote supervisory and control via the network is provided which enables users to simulate off-line and conduct the control by the network. The experiment of networked control of a DC motor by WAN with the simulation system is given. The result demonstrates the validity of the system. |
