摘　　要：实现以STC12C5A单片机为处理器的直流电机控制系统,系统通过ISP在线编程,利用PL2303 USB转串口芯片实现程序的在线调试,自动下载功能,无需专用的编程器。设计在线编程下载电路,直流电机驱动电路、速度和电流反馈电路,系统采用双闭环控制,实验结果表明系统性能可靠,具有一定应用价值。A DC motor control system based on the STC12C5A single chip microcomputer was presented. The system can program by ISP. The control program can be online debugged and automatically download by PI_2303 USB serial interface chip in this system without special programmer. The drive circuit for DC motor was designed. The feedback circuits of speed and current were designed too. The system is dual closed-loop control. The experimental result shows that the system performance is reliable and has application value.
