Abstract: To research a network control system with physical plant，a simulation platform of embedded network control system is constructed.An U-BOOT system and an embedded Linux system are transplanted and set up on the embedded hardware system based on the chip of S3C2410 and CS8900A，to construct embedded network server.This server not only communicates with physical plant directly，but also communicates with the Simulink of remote client utilizing Socket and C MEX function through the physical network.The result demonstrates that the method is feasible and has advantages of the character of physical plant and network and the stronger function of simulation.

摘要： 为了结合物理对象进行网络控制系统的研究，构建了一个嵌入式网络控制仿真平台。在基于S3C2410与CS8900A芯片的嵌入式硬件系统上，移植并安装了U-BOOT系统和嵌入式Linux操作系统，构成了嵌入式网络服务器节点。该节点既与物理对象直接通信，又利用Socket与C MEX函数与远程客户端的Simulink通过物理网络进行通信。结果表明该方法是可行的，且具有物理对象与网络的实际特性与强大仿真功能优势。
