摘　　要：本文根据级联式无刷双馈电动机统一坐标系下的数学模型,推导了电磁转矩和控制电动机定子磁链的预测方程。将基于排序法的预测控制方法引入无刷双馈电动机,摒弃了传统评价函数中的加权系数,省去了控制系统需要根据具体的控制要求反复对加权系数调节的过程。进行仿真实验,控制结果与DTC控制方法进行比较,结果证明基于预测控制的方法能够有效地减小转矩脉动、改善电流谐波,并且同样具有很好地动、静态性能。Predictive control of BDFM based on Ranking Method predictive equations of magnetic torque and stator flux is derived based on the mathematic model of BDFM in the unified coordination. By introducing predictive control based on ranking, the weighting factors in traditional evaluation functions are no more necessary, and thus we don＇t have to adjust the factors repeatly. Simulation results show that compared to DTC, the proposed method not only can decrease torque pulsation and harmonic current. But also can achieve good dynamic and static performance.
