摘　　要：针对开绕组无刷双馈电机模型复杂且耦合性强的问题,提出一种适用于开绕组无刷双馈电机的新型直接功率控制方法。通过研究定子控制绕组侧电压与功率绕组侧有功功率和无功功率间的关系,推导出基于d-q坐标系的直接功率控制状态方程,实现有功和无功功率的解耦控制。针对传统滑模控制器抖振及不连续高频开关控制等缺点,设计了基于新型趋近律的超扭曲滑模控制器,建立了开绕组无刷双馈发电机新型超扭曲滑模直接功率控制系统的仿真模型,并给出了不同工况下的仿真结果,验证了该功率方程模型的正确性和新型超扭曲滑模控制方法的有效性和鲁棒性。A novel direct power control strategy for the open-winding brushless doubly-fed machine was proposed to deal with the problem of the complex control structure and strong cross coupling terms which degrade the dynamic performance of the system.By studying the relationship between the stator control winding-side voltage and the power winding-side active and reactive power,the state equation of direct power control based on d-q coordinate was deduced to realize the decoupled control of active and reactive power.Aiming at the main shortcoming of a"chattering"phenomenon in traditional sliding mode control,a super-twisting sliding mode controller based on a new reaching law was designed.The simulation results verified the correctness of the proposed power model,and the effectiveness and robustness of the proposed control method.
