基才串口通信的直流电机PID调速系统设计

摘要

为了实现对直流电机快速、准确调速的要求，提出了一种基于串口通信的直流电机PID调速系统设计方案，并实现系统的软硬件设计。采用按键、OLED显示屏等人机交互工具进行参数设置及显示，通过PID控制器闭环反馈控制调节PWM信号，串口与上位机通信实现对数据的客观分析。测试结果表明，该系统具有运行稳定、调速准确、响应时间短等特点．达到了系统设计要求。%In order to realize the rapid and accurate to dc motor speed requirements, put forward based on the serial communication PID control system of de motor design, the design of the software and hardware system. The buttons, OLED screen man-machine interactive tools such as the parameters set and display, through the PID controller close-loop feedback control regulation PWM signal, serial ports and the upper machine communication to achieve the objective data analysis. The test results show that the system has stable operation, speed, accurate short response time and other characteristics, reached the system design requirements.
