Analysis Model for Ethernet-based CNC Embedded Implementation

AbstractIn order to make the most of system resource and improve system performance in Ethernet-based computer numerical control (CNC) system, it is very necessary to establish the performance analysis model and further adopt the codesign method from the control, communication and computing perspectives. Analyzing system architecture, time characteristic parameters of controlloop, model framework, etc. we proposed a simulation analysis model for real-time Ethernet-based CNC system. This model includes the timing effects caused by the implementation platform in the simulation. The key to establishing the model is accomplished by designing the error analysis module and the controller nodes. The proposed model is helpful for CNC system development
