本文提出了一种低速和零速时具有多个相对较强的凸极的永磁同步电机（PMSM）的位置估计方法。将各向异性谐波模型与通过电流测量发现的机器各向异性进行比较，其结果定义为误差。然后导出该误差的最小化规则并用于构建转子位置的非线性观测器。与之前的文献相比，该方法采用凸极角及其大小，因此能够估计转子位置，而不管各向异性谐波之间的比率如何。该方法在仿真和实验中得到了验证。
This paper presents a position estimation method for a Permanent Magnet Synchronous Machine (PMSM) with multiple comparably strong saliences at low and zero speed. An anisotropy harmonics model is compared to the machines anisotropy found through the current measurement, the result of which is defined as the error. Then a minimization rule for this error is derived and employed to construct a nonlinear observer for the rotor position. In contrast to previous literature, this approach employs the saliency angle and its magnitude and is thereby able to estimate the rotor position regardless of the ratio between the anisotropy harmonics. The approach is verified in simulation and experiments.
