Study of the Multi-axis Motion Controller Based on DSP

According to the development and current situation of DSP at home and abroad. Using high-speed computation ability and rich resources of TMS320F28335 chip to achieve higher real-time demand motion control in numerical control system (linear interpolation, continuous interpolation, position control, Serial communication, etc). On that basis, this paper discussed realization of hardware and software design method of this controller. Such movement controller has the perfect function and excellent performance, it often provides the multi-axis motion coordination control on the plate, and has higher control precision.
