| 摘 要： | 本文主要研究了利用单片机AT89S52产生PWM信号，从而实现对直流电机转速控制的一种方法。通过软件编程使单片机产生不同占空比的PWM信号，然后把PWM信号经过放大来驱动电机转动。这种方法具有调速精度高、响应速度快、调速范围宽和损耗低的优点，而且数字控制系统硬件电路的标准化程度高，可以实现不同于一般线性调节的最优化、非线性、智能化等控制规律。

| Abstract: | This text mainly studied the application of a list slice the machine AT89S52 creation the PWM sig- nal carry out and the direct current electrical engi- neering and turn soon a method of carrying on the control. Through a software plait the distance make list slice the machine produce different have the PWM signal of getting empty the ratio, then has been enlarged to drive electrical engineering to turn. This method has to adjust soon accuracy high and respond to speed quick, adjust soon scope breadth and exhaust a low characteristics, and number control standardizing of system hardware electric circuit degree high, can carry out to differ from general line to regulate of superior turn, not the line, intelligence turns, etc. |
