摘　　要：为了解决传统步进电机运动状态控制技术存在的控制响应时间长等多种问题,设计了基于STM32和增量式编码器的步进电机运动状态控制技术。选择STM32F417ZG芯片作为主控制芯片,同时利用增量式编码器构建芯片仿真器。在此基础上利用数字积分插补算法获取步进电机运动状态,并根据步进电机运动状态特征构建PID控制器,通过设定控制器的控制规律实现步进电机运动状态控制。实验结果表明,该技术控制下的步进电机位置误差较小,且控制响应时间较短,可以在实际中得到进一步推广。In order to solve the problems of long response time in traditional stepper motor motion state control technology, this paper designs a stepper motor motion state control technology based on STM32 and incremental encoder. The STM32 F417 ZG chip was selected as the main control chip, and the incremental encoder is used to build the chip simulator. On this basis, the digital integral interpolation algorithm is used to obtain the motion state of the stepper motor, and the PID controller is constructed according to the motion state characteristics of the stepper motor. The motion state control of the stepper motor is realized by setting the control law of the controller. The experimental results show that the position error of the stepping motor controlled by this technology is small, and the control response time is short, which can be further promoted in practice.
