基于永磁同步电机铁损模型的损耗最小控制

摘要

The PMSM model with iron loss is established and analysised.then the current of d axis which leads to minimal power loss is achieved, and thus the minimal power loss control strategy is found. The simulation results show that the copper loss of PMSM is slightly increased but the iron loss is substantially reduced.%建立并分析了永磁同步电机的铁损模型,得到使电机工作在功率损耗最小状态下的d轴电流,从而得到电机功率损耗最小的控制方案.仿真结果表明永磁同步电机的铜损略有增加而铁损大幅减少.
