摘要
针对现场总线控制系统的特点,建立了基于现场总线数控系统的基本模型。由于现场总线的通信环节的时间延时的大小决定了基于现场总线的控制系统实时性能,本文利用Matlab/Simulink工具建立基于PROFIBUS-DP的数控系统通信系统模型,通过仿真,对现场总线数的传输延时对数控系统的性能影响进行评估,为基于现场总线的CNC系统的研究与开发提供了理论依据。
The basic model of the CNC based on Fieldbus is constructed according to the characteristics of Fieldbus. The real-time of the control system based on Fieldbus is depended on the Fieldbus communication delay. Therefore, the communication model of the CNC based on PROFIBUS-DP is constructed by Matlab/Simulink tool in this paper, and the CNC performance about Fieldbus transport delay is evaluated, All of this provides the theoretic bases for the research and development of fleldbus-based CNC system.
