摘要

本文首先采用直接转矩控制(DTC)技术对异步电动机进行转速控制，然后利用模糊逻辑设计转速控制器，提高转矩响应，减小转速误差。直接转矩控制方法具有快速的转矩响应和对负载突变的鲁棒性。此外，应用模糊逻辑可以解决不可预测的问题。模糊逻辑还可以改善异步电动机的速度控制工作。结果表明，该方法显著提高了转矩响应，减小了转速误差。

Improvement of Torque Response and Reduction of Error Speed in Direct Torque Control of Induction Motor by Fuzzy Logic

In this paper, the direct torque control (DTC) technique is used for the speed control of induction motors, and then fuzzy logic is used for designing the speed controller, the improvement of torque response and the reduction of the speed error. The DTC method is utilized due to its quick torque response and robustness against sudden load variations. Also, by applying fuzzy logic unpredicted problems can be solved. The fuzzy logic also can improve the work of the speed control in induction motors. The results indicate that this approach improves the torque response significantly and reduces speed error.
