摘要
本文介绍的基于单片机的直流伺服电机调速系统,以低价位的P87LPC768单片机为核心,利用自带的PWM信号发生器以及丰富的中断资源,实现了对直流伺服电机转速的实时检测和闭环控制。
A gemeral control way for rotate speed of direct current servo electromotor is hardware circuit, it is used for many years in practice. But the hardware is complex and difficult to adjust the velocity, so it is not flexible. The paper presents a system to regulate the speed of a DC motor by using the PWM function of P87LPC768.
