摘　　要：以两相混合式步进电机为研究对象,基于STM32单片机和THB6064MQ细分功率驱动芯片,设计并研制出一套步进电机控制系统。通过按键或语音识别两种方式向系统发出控制指令,改变转向、步距角、运行频率和步数等步进电机运行参数,并通过OLED显示屏实时将运行状态可视化。给出总体设计方案,设计了包括最小系统、驱动电路、电源转换电路、按键电路等硬件电路,给出步进电机转速控制、指数型加速曲线、主程序和中断服务程序等软件设计。学生通过该项目可以很好地锻炼综合实践能力,为创新设计打下良好基础。Based on STM32 microcontroller and THB6064MQ subdivision power drive chip,a stepper motor control system is designed and developed in this paper with two-phase hybrid stepper motor as the research object.Control commands are sent to the system through keystroke or voice recognition to change the running parameters of the stepper motor,such as steering,step angle,running frequency and step number,and the running state is visualized in real time through the OLED display screen.The overall design scheme is given,the hardware circuit including the minimum system,the drive circuit,the power supply conversion circuit,the key circuit and so on is designed,and the software design including the speed control of the stepper motor,the exponential acceleration curve,the main program and the interrupt service program is completed.Through this project,students can exercise their comprehensive practical ability and lay a foundation for innovative design.
