直接转矩控制的原理与应用

以ABB公司ACS600Single Drvie变频器为例介绍了异步电动机直接转矩控制的基本原理与实现方法，着重阐述了电机模型建立方法，转矩与磁链滞环控制器的功能，脉冲优化选择器的要求，直接转矩控制技术是近十几年继矢量控制变频调速技术之后发展起来的一种新型的高频交流变频调速技术。

Principles and Application of Direct Torque Control

Taking ACS 600 Single Drive frequency converter made by ABB, the basic principle of direct torque control of an asynchronous motor and operation methods are presented. The establishing method of a motor model, function of torque and flux linkage block ring controller and requirements for pulse optimum selector are described in detail. The direct torque control technique is the new technique of A.C. frequency conversion speed control with high performance developed after the technique of frequency conversion speed control of vector control.
