提出了一种新型的基于虚拟信号注入的内置式永磁同步电机（IPMSM）最大转矩/电流（MTPA）控制方法。所提出的方法注入一个小的虚拟电流角信号数学跟踪MTPA的工作点，并产生d轴电流指令，通过利用MTPA操作的固有特性。该方法在跟踪MTPA点时与参数无关，并且不向电流或电压指令注入任何真实的信号。因此，可以避免与真实的高频信号注入相关的问题，例如铜损和铁损的增加。此外，它是强大的电流/电压谐波和电机转矩干扰。所提出的方法进行了验证，在各种操作条件下的原型IPMSM驱动系统的仿真和实验。
This paper introduces a novel virtual signal injection-based control method for maximum torque per ampere (MTPA) operation of interior permanent magnet synchronous machine (IPMSM) drives. The proposed method injects a small virtual current angle signal mathematically for tracking the MTPA operating point and generating d-axis current command by utilizing the inherent characteristic of the MTPA operation. This method is parameter independent in tracking the MTPA points, and it does not inject any real signal to current or voltage command. Consequently, the problems associated with real high-frequency signal injection, such as increases in copper and iron loss can be avoided. Moreover, it is robust to current/voltage harmonics and motor torque disturbances. The proposed method is verified by simulations and experiments under various operating conditions on a prototype IPMSM drive system.
