ATmega162单片机与交流电机调速控制研究

AC motor speed control based on ATmega162 SCM

在交流电机调速控制系统里,可以利用ATmega162单片机进行通信及脉宽调制,并且需要开发单片机与上位计算机进行串行通信的控制界面.给出了交流电机移相调速控制及脉宽调制在ATmega162中的编程实现过程,阐述了使用C语言编写的单片机串行通信接口程序,并说明了利用Delphi编写计算机串行通信界面的方法.

In an alternating current (AC) motor speed control system, communication and pulse width modulation (PWM) can be realized based on anATmega162, single chip microcontroller (SCM), specifically for control interfaces between SCM and host PC. In this study, a novel method is proposed to deal with SCM-based moving-phase speed control and PWM. Finally, this system is programmed via C TM and Delphi TM for serial-communication ports and interfaces, respectively.
