A dynamic control method and device of a stepper motor and a position following system

Abstract

This application provides a dynamic control method, device, electronic device, and position following system for a stepper motor. The dynamic control method includes: acquiring the target position of the stepper motor in the position following system during a target control cycle; controlling the stepper motor to run and recording the number of acceleration steps during the acceleration phase; calculating the remaining number of steps to the target position; and controlling the running state of the stepper motor according to the number of acceleration steps and the remaining number of steps, so that the stepper motor reaches the target position. Unlike traditional linear acceleration and deceleration, it does not require pre-calculation of acceleration steps, constant speed steps, and deceleration steps. Instead, it directly relies on the actual position fed back by the encoder to determine the running state of the motor, realizing the position following function in the dynamic system. It adjusts the acceleration and deceleration characteristics according to the motor characteristics, thereby achieving a good response speed.
