表贴式永磁同步电机驱动的零d轴电流I-f控制

This article deals with I-f control of surface-mounted permanent magnet synchronous machine (SPMSM) drives. Conventional open-loop I-f control is poorly damped and can only operate stably with positive $d$-axis current. An I-f control with a new current compensation loop is proposed to achieve stable $i_{\mathrm{d}}=0$ operation in this work. The proposed method can be used for startup with a seam...
