摘　　要：针对教学过程中学生难以理解直流伺服电机控制系统工作原理这一问题,开发了一种直流伺服电机控制系统。实验系统基于LabVIEW软件进行上位机人机界面设计和单片机控制程序的编写,运用STM32单片机和相关芯片构成单片机控制系统硬件,直流电机加编码器代替直流伺服电机,实现了电机速度控制采集、PID控制原理展示。运用该系统,可以实时调整PID参数和获取电机速度曲线,易于实现PID参数整定和二次开发,从而加深学生对直流伺服电机控制原理的认识和理解。Aiming at the problem that students have difficulty understanding the working principle of the DC servo motor control system during the teaching process,a DC servo motor control system was developed.The experimental system is based on LabVIEW software for the design of the host computer interface and the writing of the microcontroller control program.STM32 single-chip microcomputer and related chips are used to form the single-chip microcomputer control system hardware.DC motors and encoders are used instead of DC servo motors to realize motor speed control acquisition and PID control principle display.By using this system,PID parameters can be adjusted in real time and the motor speed curve can be obtained.It is easy to realize PID parameter tuning and secondary development,thereby deepening students’understanding and comprehension of the principle of DC servo motor control.
