考虑电压误差和参数变化的永磁同步电机无信号注入及专用测试参数估计

This article proposes an offline noninvasive method for the parameter estimation of permanent magnet synchronous motors controlled with nonzero $d$-axis current. The proposed algorithm has been specifically designed to operate in application scenarios, where custom signal injection and dedicated test campaigns are not possible and are potentially characterized by scarce measurement data variety.
