Title    The Design and Application of Motion Control    System Based on FPGA                       

Abstract The main task of this paper is to illustrate the design and application of a robot’s control system, with the background of ABU ASIA-PACIFIC ROBOT CONTEST 2013  qualifying trial in China. This paper introduces the robot mechanical structure briefly, details the design and production of robot’s control system with DSP and FPGA as the core. FPGA is used as the slave computer of the control system to imple-ment these features: collecting the signals of sensors such as optical fiber and infrared optoelectronic switch, filtering pre-processing, motion control, and other functions. The peripheral circuit of the infrared optoelectronic switch is introduced in detail, the sche-matic diagram is drawn, appropriate components are selected and a PCB is made. The obtained and processed signals are sent to the principal computer DSP by the commu-nication interface. FPGA controls the DC motor and digital servos by corresponding I/Os to implement motion control according to the instructions sent by DSP .FPGA forms the feedback in the system which optimizes the control system through the communication with DSP.
