一种考虑直流母线电压限制的表贴式永磁同步电机转矩脉动抑制谐波电流控制新方法

Torque ripple reduction based on harmonic current injection has been widely applied to surface-mounted permanent-magnet synchronous machine (SPMSM) drive systems. However, additional voltages are typically required for harmonic injection, and the dc-link voltage limit should be considered in practical drive systems. This article proposes a novel harmonic control for SPMSMs in which the torque ripp...
