摘要 TCP/IP协议已经成为了网络化控制系统中事实上的传输标准协议,但TCP/IP协议直接用于网络化控制系统中还存在实时性不足,开销过大等问题,特别是针对网络化控制特殊环境下的TCP建模分析还缺乏研究。本文针对网络化控制中的数据流特点,建立了数据传输的TCP解析模型,分析了一些重要的参数。实验结果表明,该模型较好地反映了实际网络化控制中的TCP传输行为,可以作为分析和改进网络化控制中TCP协议的模型。 TCP/IP is actually the standard transmission protocol of the networked control systems. But some issues such as real time and cost of the protocol obstacle the application of it in networked control systems. The work on TCP modeling in networked control environment has not been done so much. This paper establishes the TCP analytic model according to character of data flow in networked control systems. Some concerned parameter is analyzed. The experiment result shows that this model is well validated with the real TCP behavior of networked control and can be used as the model to analysis and promote the TCP performance of networked control systems.
