Research of Ethernet communication technology for motion control

Abstract

For Ethernet-based motion control application, this paper analyze system function, system architecture, and performance requirements of motion control system, and proposed an improved Ethernet communication method. The method, which bases on the time slice and priority strategies, schedules data to be transmitted deterministically and meets the motion control real-time processing requirements without changing the fundamental communication mechanism of Ethernet. The final results of test verify the feasibility of Ethernet-based real-time control application for motion control.
