英文摘要：

Faced with the trend of high-precision, high-efficiency, networking and modularization of the control system, a networking control system with multi-axis linear motor is designed. The advantages and methods of linear motor working at precision positioning platform are introduced, of which the implementation to construct networking control system based on MODBUS/TCP protocol is discussed specifically. HMI is realized through the Ethernet, which realizes the movement control and the real-time acquisition of the state information. Conclusion The sports platform is of high-precision and system stability, whose repeatability positioning accuracy is less than 1.
