Research on Remote DC Motor Control System Based on FPGA
In order to solve the real-time and accuracy problem of motion control systems in outfield test,a motor motion control system based on Ethernet transmission by field programmable gate array(FPGA)was proposed.The upper computer is used to re-motely control the multiple DC motor directions,speeds,positions,achieving the combination of software and hardware.It adopts the YT8511/H chip,RGMII interface,and Altera official IP core to build the high-speed Ethernet communication interface for FPGA.Besides,the UDP communication protocol was realized by using the three-stage machine,and the motor position feedback was com-pleted through the 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 test-ed and simulated.The results indicate that the system meets the requirements of remote control,with a positioning accuracy of 0.09°,and it has a good portability.
