摘要
针对无刷双馈电机矢量控制策略里转速环和无功功率控制环耦合较大的问题,提出了具有解耦补偿的矢量控制策略。此控制策略基于功率绕组电压定向坐标系,可以对电机转速和无功功率实现解耦独立控制,同时避免了定子磁链的计算。通过搭建的实验平台进行了变速调频实验研究,证明了所提出的控制方法具有良好的动态性能和解耦补偿能力。
A Compensation Decoupling Control scheme is proposed for the Brushless Doubly-Fed Machine(BDFM)based on the PW(Power Windings,PW)voltage oriented generalized vector model for the coupling between the speed control loop and the reactive power control loop.The control scheme can realize the decoupling control of speed and reactive power and avoid the calculation of the stator flux-linage.An experimental platform has been built,and experimental results show that the proposed controller has good performance and good decoupling performance.
