摘要
介绍了基于单片机用PWM实现直流电机调整的基本方法,直流电机调速的相关知识,及PWM调整的基本原理和实现方法。重点介绍了基于MCS-51单片机的用软件产生PWM信号的途径,并介绍了一种独特的通过采用计数法加软件延时法实现PWM信号占空比调节的方法。对于直流电机速度控制系统的实现提供了一种有效的途径。
This paper introduces a kind of method of DC - motor speed modification based on PWM theory by the SCM. Showing some relative knowledge upon the DC - motor timing, the basic theory and the way to implement. And it emphasizes on the way for carrying out PWM signals based on MCS-51. This paper still provides a method for modifying the speed of DC - motor by way of taking count of data and time delay by software. It offers a sort of efficient method for the DC motor speed - controlling system.
