摘　　要：单片机控制的变频调速系统设计思想是用转差频率进行控制。通过改变程序来达到控制转速的目的。本文介绍了该系统的组成和实现方法。The design thought is that the speed control system of frequency conversion based on one-chip computer is controlled with the frequency of difference of rotational speed. And the rotational speed is controlled through changing the procedure. This article introduces the composition and realization of this system.
