A new closed-loop control method is used for the control system of stepping motor, general structure and main modules of the system are briefly introduced. Then the open-loop and closed-loop algorithms are contrasted and the digital closed-loop PID method is improved based on practice. The result indicates that the closed-loop control method acquires better effect and has a higher precision than openloop. This control method can also avoid the problems of open-loop such as surge, step lose.
