Abstract:The servo control system based on DSP and FPGA can meet the requirements plex control⁃
ling arithmetic. By analyzing the functions and features of DSP chip from ALTERA Co. and FPGA chip from FP⁃
GA Co. and integrating munication between CAN bus and puter, a tracking controller is de⁃
signed based on DSP, FPGA and CAN bus. And its function and hardware structure as well as software flow design
are described. Its hardware source selection, operation principle, basic function module construction and algorithm
realization modes are emphasized. The controller can meet the requirements of high-speed tracking servo system
on the areas of real time, accuracy and stability and has good
