Title:
METHOD, APPARATUS AND SYSTEM FOR CONTROLLING STEPPING MOTOR, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/042637
Kind Code:
A1
Abstract:
A method, apparatus and system for controlling a stepping motor (1003) and a storage medium, the method comprising: providing a sinusoidal S-curve acceleration algorithm; according to a target displacement and a target velocity, by means of the algorithm, calculating and planning a velocity equation of the stepping motor (1003) during movement; and according to the velocity equation, controlling the stepping motor (1003) to operate by a high-performance processor and a driving module (1002) built into a driver. Since the second derivative of the velocity equation thereof is a sine function, i.e. acceleration and jerk equations are both continuous and derivable, and there is no sudden change, same conforms to the characteristic in which the torque of the stepping motor (1003) decreases along with an increase in velocity, thereby making full use of the effective torque of the motor. At the same time, mechanical shock may be weakened, so that the stepping motor (1003) operates more smoothly and reliably.
