摘要
现在许多单片机具有PWM脉宽调制功能,结合单片机的定时器、计数器,我们可以很方便的实现电机的恒速驱动。本文以编码器为反馈信号,构成了电机恒速转动的闭环系统。
Now many Single Chip Microcomputer with PWM pulse width modulation, combined with Single Chip Microcomputer timer and counter, we can easily achieve the constant speed drive motor, ln this paper, encoder acts as feedback signal, constitutes a constant speed motor rotating closed-loop system.
