模糊控制技术在异步电机直接转矩控制中的应用

Application of Fuzzy Control Technology in the Direct Torque Control of an Induction Motor

采用模糊控制器取代施密特触发器以实现模糊直接转矩控制,并采用模糊速度调节器,进一步提高了系统的性能。仿真结果表明系统的速度响应加快,鲁棒性增强。

In this paper, fuzzy direct torque control system is set up through fuzzy controller to replace Smith flip-flop and a fuzzy speed controller is used to improve its performance. Simulation results indicate that the system has rapid speed response and strong robustness.
