摘要
直接转矩控制一种高效变频调速技术,是继矢量控制技术之后的又一种新的控制思想;其控制手段直接,系统响应迅速,具有优良的静、动态特性,系统鲁棒性好,因而受到普遍关注并得到迅速发展。文章从直接转矩控制技术的初期发展,分析了异步电机直接转矩控制的基本原理,介绍了直接转矩控制技术的研究现状和研究方向,并说明了无速度传感器,已成为直接转矩控制系统研究的重要内容。
The paper presents a high-efficiency variable-frequency adjustable-speed technology, the Direct Torque Control. The technology is another new control thought after vector-control technology. It has direct control methods, rapid response system, excellent static and dynamic characteristics and the system's robustness is good, so DTC has been widely studied and has achieved rapid development. This paper illustrates the development of DTC technology and then analyzes the basic principle of induction motor direct torque control. Then, it shows the present research of DTC. research tendencies .And it also shows that the research of Speed sensor-less has became one of the important research about DTC system.
