Harmonic Injection-Based Torque Ripple Reduction of PMSM with Improved DC-Link Voltage Utilization

This letter proposes an improved scheme for torque ripple reduction of permanent-magnet synchronous machines (PMSMs) considering dc-link voltage utilization. Different from the previous methods, both q -axis and d -axis harmonic currents are optimized and injected. Specifically, the appropriate q -a...
