双馈风力发电系统采用传统矢量控制时，利用PI控制器，但此控制器不易调节参数，动态性能和鲁棒性较差。为改善控制器性能，提出一种新型高阶滑模控制器，明显改善传统滑模控制的抖振现象，将高阶滑模控制与传统矢量控制相结合应用到双馈风力发电系统功率控制中。仿真结果表明，高阶滑模控制器相比传统PI控制器，具有更好的动态性能，鲁棒性更强。

The PI controller is used in the traditional vector control system for the doubly fed wind power genera?tion system, but it is not easy to adjust the parameters with the controller, and the dynamic performance and robust?ness are poor. In order to improve the control performance of the controller, a new high order sliding mode control?ler was designed in this paper to improve the chattering phenomenon of conventional sliding mode control, then the control strategy of combining high?order sliding mode control with the traditional vector control was applied to the doubly fed wind power generation system control. The simulation results show that the high order sliding mode con?troller has better dynamic performance and stronger robustness than the conventional PI controller.
