Abstract

This paper presents a new control method to synchronize multiple stepper motors with acceleration and deceleration. The S-shape velocity profile is chosen to generate a frequency look-up table. Adjust the look-up table by multiplying a factor by the frequency for each stepper motor in real time so that the tables have equal time length. In the meanwhile, the velocity still shows the S shape. Since this method only saves one look-up table in memory and needs simple calculation in real time, it can be used in low-end microcontrollers. The method was tested using three stepper motors on the Arduino platform and the result shows good time accuracy and good performance.
