基于模型预测转矩控制的五相磁通切换永磁电机开路故障容错策略
|
摘要
为了提高单相开路故障下五相磁通切换永磁电机的控制性能,将模型预测转矩控制技术应用于其容错控制中。为了实现对基波和谐波空间状态的综合控制,该研究选择转矩、磁链幅值和谐波空间电流作为控制目标。针对容错算法中模型预测控制计算量大的问题,根据直接转矩控制中设置开关状态表的思想,提出一种基于电压矢量预筛选的模型预测转矩控制策略。该方法通过确定定子磁链所处的扇区位置,并结合转矩和磁链幅值的变换,通过查表法选定对应的电压矢量集作为预测模型的备选矢量,能够在满足控制性能的基础上有效地降低遍历次数,实现简化计算。最后,通过仿真和实验,验证所提模型预测转矩控制策略的有效性。
To improve the fault-tolerant performance of five-phase flux-switching permanent magnet(FSPM) motor under open-circuit fault, the model predictive torque control(MPTC) was investigated. For the comprehensive control of the fundamental and harmonic subspaces, the torque, the amplitude of the stator flux linkage and the current in the harmonic subspace were employed as the control targets. Moreover, a pre-selective method, which was inspired by the switching table in the direct torque control, was developed to reduce the number of active switching states as well as the computational burden. By combining the sector where the stator flux linkage is located with the variations of the torque and the stator flux linkage magnitude, the specific voltage vectors instead of all vectors were determined as the vector candidates. As a result, the number of traversals was effectively reduced, and the computational burden was significantly alleviated. Consequently, the effectiveness of the proposed MPTC methods had been validated by simulations and experiments.
