Abstract: The dual-axis motor drive system was designed based on DSP and CPLD. In the system TI DSP TMS320LF2808 is selected as the main control chip, implement two motor’s three-loop control. Altera CPLD using the company’s EPM570, complete with the host computer and the optical encoder interface extensions, greatly reduced the volume of the system, to enhance the system’s immunity and confidentiality. The results show that this system hardware and software design is reasonable, better performance, high reliability used in Flat Knitting Machine.
