异步电机矢量控制系统模糊PI控制器设计

采用传统PI控制器的异步电机矢量控制系统响应有延迟,调整过程中有超调。为改善异步电机矢量控制系统的动态性能,文中采用模糊矢量控制策略对三相异步电机进行控制,能够获得较好的动稳态性能。在Matlab/Simulink环境下,对模糊矢量控制策略进行了仿真研究,仿真实验结果表明,该控制策略能够获得快速的动态响应、转速无超调、系统鲁棒性更强的效果。

The Design of the Fuzzy PI Controller for the Asynchronous Motor Vector Control System

The response of the asynchronous motor vector control system is slow,which uses traditional PI controller. And the control system has overshoot in the adjustment process. To improve the dynamic performance of the asynchronous motor vector control system,this thesis applies fuzzy vector control strategy to control the three- phase asynchronous motor. It can get a better dynamic and static performance. The fuzzy vector control strategy has been researched and simulated under the Matlab / Simulink environment. The simulation result shows that the control strategy can get fast dynamic response,no speed overshoot and stronger system robustness.
