在本文中，提出了一种基于虚拟高频信号注入的搜索方法，用于推导出内置永磁同步电机（IPMSM）驱动系统每安培最大效率控制的最佳电流角。它将一个小的虚拟方波高频信号注入到包括电机和逆变器的IPMSM驱动系统的数学模型中，从而可以准确地导出最佳电流角。最后在1kW原型IPMSM上进行了测试，显示出良好的搜索精度和动态性能，同时由于虚拟化信号注入，系统损耗和扭矩纹波不会增加。
In this article, a virtual high-frequency signal injection based searching method is proposed to derive the optimal current angle for the maximum efficiency per ampere control of interior permanent magnet synchronous machine (IPMSM) drive system. It injects a small virtual square wave HF signal into the mathematical model of IPMSM drive system including both the electrical machine and inverter, by which the optimal current angle could be accurately derived afterward. It is finally tested on a 1-kW prototype IPMSM and shows a good searching accuracy and dynamic performance while the system loss and torque ripple will not increase thanks to the virtualized signal injection.
