交流异步电机变频调速系统矢量控制与直接转矩控制算法比较

Comparison of Vector Control and Direct Torque Control on AC Motors

介绍了交流异步电机变频调速系统现在常用的矢量控制理论与直接转矩控制理论。通过比较给出了这两种控制算法的各自特点,旨在通过研究可以提高交流电机控制的精确度与稳定性。

The paper introduces the theory of vector control system and direct torque control. And the two algorithms have their own characters. So it is hoped that the accuracy and stability of the AC motor control will be improved basedon the study.
