For the voltage space vector close loop control-based strategy, based on the proportional-plus-integral-based control scheme, a new control scheme composed of an adaptive resonant controller and a PI controller is proposed in the paper, by which the stator voltage waving is almost elimited, and a very well control performance is achieved for stator voltages, naturally, the softly cut-in control is realized.

针对基于空间电压矢量闭环控制的这一投切方案，在PI调节器控制的基础上提出了自适应谐振调节器与PI调节器并行控制的控制策略，有效抑制了定子电压幅值的波动，使定子电压具有较好的控制响应，进而实现了双馈风力发电机零电流切入电网的目的。
