    摘要:

    針對外場(chǎng)試驗中運動(dòng)控制系統實(shí)時(shí)性與準確性問(wèn)題,提出了以FPGA為核心的以太網(wǎng)傳輸電機運動(dòng)控制系統方案。通過(guò)上位機完成對多個(gè)直流電機方向、速度、位置等的遠程控制,實(shí)現了軟硬件相結合。采用YT8511/H芯片、RGMII接口和Altera官方IP核搭建了FPGA的高速以太網(wǎng)通信接口,運用三段式狀態(tài)機實(shí)現了UDP通信協(xié)議,通過(guò)增量式光電編碼器完成電機位置反饋,以Verilog硬件描述語(yǔ)言為基礎,編寫(xiě)了電機驅動(dòng)程序和編碼器信號處理程序,對系統的通信、輸出脈沖以及編碼器信號處理進(jìn)行了實(shí)驗和仿真。結果表明,系統滿(mǎn)足遠距離控制需求,定位精度可達0.09°,有較好的移植性。

    Abstract:

    In order to solve the real-time and accuracy problem of motion control system in outfield test, a motor motion control system based on ethernet transmission by field programmable gate array (FPGA) was proposed. Remote control of multiple DC motor directions, speeds, positions, etc. was accomplished through the upper computer, achieving the combination of software and hardware. By using YT8511/H chip, RGMII interface, and Altera official IP core, a high-speed Ethernet communication interface for FPGA was built. Besides, the UDP communication protocol was realized applying a three-stage machine and the motor position feedback was completed through a incremental photoelectric encoder. Based on Verilog hardware description language, the motor driver program and encoder signal processing program were written, and the system communication, output pulse and encoder signal processing were tested and simulated. The results indicate that the system meets the requirements of remote control and has good accuracy and portability. Also, the positioning accuracy can reach 0.09 °.
