【Abstract】 The motion control of stepping motor in the servo system is investigated and a motion control module based on digital signal processor is designed. This module adopts close-loop control to enhance the accuracy and performance of the system and utilizes CPLD to simplify the structure of the hardware system, thus reinforces the stability and reliability of the system. In addition, this paper also analyzes the control of speed change of the stepping motor.更多还原
