Design of DSP based multiple stepping-motors´ micro-stepping driving controller

This paper proposes a design of a multiple stepping-motors´ micro-stepping driving controller which based on DSP and CPLD circuits. It first introduces the principle of micro-stepping control and power driving of multiple stepping-motors. Then it explains the hardware and software that was particularly designed for micro-stepping driving controller of multiple stepping-motors with the technical requirements for the robot assistant microsurgery system. It also gives the experimental results in different situations. The experimental results demonstrate that the driving controller satisfies the technical requirements of a robot. At last, the paper summarizes the performances of the driving controller and briefly forecasts its further applications.
