“…In the low-speed segment, it is multiplied by the correction function in (10). The experiment found that the exponential function is the best choice for the correction function: The segmented function velocity time formula modified by ( 5) and ( 10) is: (11) At this point, the probability of faults occurring in the high-frequency and low-frequency bands of the stepper motor is greatly reduced, but the derivative of (12) yields the corrected acceleration time (12) for the curve:…”

To improve the open-loop control performance of stepper motors, research was conducted on their operating curves. The acceleration-velocity characteristic equations of three common operating curves were established and compared with the torque frequency characteristic curves of stepper motors. Based on this, an improved segmented correction fitting S-shaped (SCFS) curve design method based on a high torque utilization sine curve was proposed to solve the problem of rotor blockage and overshoot caused by uneven acceleration during the operation of stepper motors. In the simulation of the stepper motor load motion system, the SCFS curve was compared with common curves. The simulation results showed that the position tracking error was reduced by approximately 82% compared to the trapezoidal curve and approximately 70% compared to the exponential curve. Research has found that this method is suitable for the design of high-precision motor operating curves and has a high application value in the field of precision motion control.
