Abstract

In recent years, the synchronous reluctance (SyncRel) motor received much attention for many applications due to its simple and robust construction. When using the principle of vector control, it is possible to achieve optimal operation of SyncRel motors for all loads and speeds. A suitable control strategy can be implemented to achieve maximum torque per ampere, high efficiency and maximum power factor. However, the control of a SyncRel motor is highly affected by both magnetic saturation and high iron losses. A new strategy to achieve maximum torque per ampere (MTPA) is proposed in this paper. The motor behavior under vector control is analyzed considering both saturation and iron losses. A simple relationship between the developed torque and d-axis current has been obtained for MTPA conditions. After experimental check, the obtained relation has been implemented in a vector control algorithm. The proposed control strategy has been successfully implemented with the aid of an experimental setup.

考虑饱和损耗和铁损的同步磁阻电机每安培最大转矩矢量控制策略

近年来，同步磁阻(SyncRel)电机因其结构简单、坚固耐用而受到广泛关注。当使用矢量控制原理时，可以实现SyncRel电机在所有负载和速度下的最佳运行。采用合适的控制策略可以实现最大转矩/安培、高效率和最大功率因数。然而，SyncRel电机的控制受到磁饱和和高铁损耗的高度影响。提出了一种实现最大转矩/安培(MTPA)的新策略。分析了矢量控制下电机的饱和损耗和铁损耗。在MTPA条件下，得到了转矩与d轴电流之间的简单关系。经实验验证，得到的关系已在矢量控制算法中实现。在实验装置的帮助下，所提出的控制策略已成功实现。
