“…The control method of a stepping motor includes open-loop control and closed-loop control. The closed-loop method forms the closed-loop through detecting the position of a motor rotor, carries a fuzzy proportional-integral-derivative (PID), space vector pulse width modulation (SVPWM) and other control technology in the traditional closed-loop control to make the system have better control performance and dynamic response, but the complexity and cost of the closedloop control system are higher [2][3]. The closed-loop control is the right choice stepper motor, it is used in complex applications where use is more important than cost [4].…”

The study of the subdivision driving technology of a stepper motor and two types of typical acceleration and deceleration curves aims at optimizing the open-loop control performance of the stepper motor. The simulation model of a two-phase hybrid stepper motor open-loop control system is set up based on the mathematical model of the stepper motor, in order to let the stepper motor have the smaller stepper angle, two types of typical acceleration and a deceleration curve algorithm are designed for the realtime online calculation based on the subdivision driving technology. It respectively carries out the simulation analysis for their control effects. The simulation results show that the parabolic acceleration and deceleration curves have a larger maximum in-step rotation angle and the faster dynamic response ability in the same control period, and at the same time, the position tracking error of an intermediate process is smaller.
