摘要
针对无刷双馈电机(BDFM)结构的复杂性、随环境的可改变性及传统的PID控制在BDFM中应用不理想等,提出了一种新型基于扩张观测器的非线性PID控制——自抗扰控制方法来实现对风力发电系统有功功率和无功功率的解耦控制。仿真结果证明了该方法的正确性和有效性,具有更强的鲁棒性和可实现性。
Owing to the complexity of BDFM structure, parameters convertibility with environment and application of traditional PID control to BDFM having some shortcomings, this paper proposes a new non-linearity PID control based on extended state observation, that is auto-disturbance resistant control, to realize decoupling control active and reactive power of wind power generation system. The simulated results show that the proposed method is correct and effective, which has robust and is easy to he implemented.
