全微机化DTC变频调速系统

A Fully Micro-Computerized Variable Frequency Speed Control System with DTC

异步电动机直接力矩控制（DTC）是一种新的高性能交流调速系统，本文介绍了用8098单片机实现的全微机化DTC控制系统，提出了一种简单、实用、高精度的电动机转速数字检测方法，在VMOS变频器上对系统进行了实验研究，结果表明该系统不仅结构简单，性能也不亚于矢量控制的变频调速系统。

Asynchronous motor direct torque control is a new speed control system of high effcienty.The fully computerized DTC system based on MCS-8098 is presented in this paper. A simple,practical and high critical digital speed measuring method for motor is also given. The system has been tested on VMOS variable frequency instruments. The results show it is not only simple in construction,but its properties are not inferior to the system with the vector control.
