永磁同步电机驱动中齿槽效应与交叉耦合效应的电流控制分析与抑制

This paper proposes a d-q cross-coupling current controller for permanent magnet synchronous motor (PMSM) drives. Slotting and cross-coupling effects in PMSMs cause the effective air-gap length to vary with the rotor angle and distort the distribution of the air-gap flux. Such distortions have a significant influence on the current control by changing the relationship between the stator currents a...
