摘要：基于扩张状态观测器的自抗扰控制器具有不依赖于被控对象的具体数学模型，并对内外扰动有较强的抗干扰能力的特点，通过非线性配置构成的非线性状态误差反馈控制律。本文将自抗扰控制方法引入双馈风力发电功率控制系统中有功与无功的解耦控制，并对自抗扰控制器进行了详细设计及参数整定，使控制系统具有良好的适应性和鲁棒性，且具有无超调、无静差的控制效果。仿真结果展现了基于自抗扰控制的双馈风力发电系统功率控制的优良特性，验证了该控制策略的有效性。

Abstract: Autodisturbance rejection controller with extended state observer is independent of the controlled objects specific mathematical model, and has features of a strong antijamming ability for internal and external disturbance by linear configuration of the nonlinear state error feedback control law. This article introduced ADRC to active and reactive power decoupling control of doublyfed wind power generation system, and detailed design and parameter tuning of ADRC were presented, so the control system has good adaptability and robustness without overshoot and static deviation. The simulation results show the fine features of ADRC control to doublyfed wind power generation system, and verify the effectiveness of this control strategy.
Key words: DFIG; power control; autodisturbance rejection controller; decoupling control
