An Adaptive Harmonics Suppression Strategy Using a Proportional Multi-Resonant Controller Based on Generalized Frequency Selector for PMSM

Actuators
In permanent magnet synchronous motor (PMSM) drive systems, the nonlinearity of the inverter and non-sinusoidal nature of back EMF generate harmonics in the stator current, resulting in torque ripple and reduced motor efficiency.
