直驱永磁风力发电机的变流器通常采用基于PI矢量控制。传统的PI控制需要进行复杂的坐标变换，引入交叉耦合项和前馈补偿项，会影响系统的鲁棒性和动态响应效果。针对此类问题，提出一种改进的PR控制器，将其应用于直驱永磁风力发电机的变流器。分析其原理，并在PSCAD中建立系统仿真模型，验证改进的PR控制器的优势，证明该控制策略应用在直驱永磁风力发电机变流器中的有效性。

Generally, the converter of direct-drive permanent magnet wind turbine uses vector control strategy which is based on PI controller.The traditional PI controller needs complex coordinate transformation, and adds the cross-coupling terms and compensation terms of feed-forward,and all this will affect the robustness and the dynamic response performance of the system.To solve such problems, this paper presents an improved PR controller, and applies it to the direct-drive permanent magnet wind turbine converter system.Through analyzing the principles, and establishing the system simulation model in PSCAD, and verifying the improved PR controller′s advantages, it proved the effective-ness of the application of improved PR controller in the converter system of direct-drive permanent magnet wind tur-bine.
