Abstract

This application is applicable to the technical field of motor control, and provides a stepping motor synchronous driving method, device, terminal and storage medium. The stepping motor synchronous driving method includes: obtaining the first speed signal of the first motor and the second motor The second rotational speed signal; and determine the first pulse signal according to the first rotational speed signal, determine the second pulse signal according to the second rotational speed signal; then determine the first target frequency compensation value according to the first pulse signal and the preset value, and determine the first target frequency compensation value according to the second rotational speed signal The pulse signal and the preset value determine the second target frequency compensation value; then determine the first target pulse signal according to the first pulse signal and the first target frequency compensation value, and determine the second target according to the second pulse signal and the second target frequency compensation value Pulse signal; finally, the first motor is driven according to the first target pulse signal, and the second motor is driven according to the second target pulse signal, so as to realize precise control of synchronous driving of the first motor and the second motor.

Description

technical field [0001] The present application belongs to the technical field of motor control, and in particular relates to a stepping motor synchronous driving method, device, terminal and storage medium. Background technique [0002] The stepper motor is an open-loop control element that converts the electrical pulse signal into angular displacement or linear displacement. The speed and stop position of the stepper motor only depend on the frequency and number of pulses of the pulse signal. The stepper can be controlled by controlling the number of pulses. The angular displacement of the stepper motor can be controlled to achieve accurate positioning; at the same time, the rotation speed and acceleration of the stepper motor can be controlled by controlling the pulse frequency, so as to achieve the purpose of speed regulation. [0003] In industrial servo control, the dual-motor synchronous drive mode of the shaft system has been widely used. Compared with the single-moto...
