This course is designed to realize PWM governor are turning, inversion, accelerate, slowing down, stop the operation. To realize the microcomputer control system, in design, the paper describes-51 SCM as the whole control system control circuit of the core part, match with all kinds of display, driver modules, realize the motor speed parameters of the display and measurement; By the command input module, H driver module. The interruption of independent type with keyboard as a command input, microcomputer in the program under control, and constantly drive circuit to send the PWM, H drive circuit complete motor positive negative control. In the design, the speed, by changing the way PWM PWM accounted for empty to change the motor than armature voltage, and achieve the speed of motor. The design of the control system in the hardware structure, use a lot of integrated circuit module, greatly simplified the hardware circuit and improve the stability and reliability of the system, the system of the performance improved. Finally, we give system program flow chart. Keyword: DC motor MSC-51 single-chip microcompute PWM speed regulation 前言 当今，自动化控制系统在各行各业得到了广泛应用和发展。而直流电动机具有良好的起动、制动性
