To address the issue of harmonic concentration near fixed switching frequencies caused by high-speed switching actions in traditional PWM strategy, the random modulation strategies in the PMSM servo drive system are studied. On the basis of conventional RSF-PWM strategy, DRM-PWM strategy enhances EMC by introducing randomization of the zero-vector action time. However, this strategy struggles to balance EMI suppression effectiveness with system control performance. Subsequently, MARSF-SVPWM strategy is investigated, with a focus on comparing and analyzing the two modulation strategies. Compared to DRM-PWM strategy, MARSF-SVPWM strategy maintains overall spread spectrum range and average switching frequency while narrowing the distribution range of differences between adjacent switching frequencies, thereby further reducing harmonic peaks. Simulation and experimental results demonstrate that MARSF-SVPWM strategy achieves better harmonic dispersion performance compared to DRM-PWM, and maintains a lower impact on system control performance, optimizing the EMI suppression effect.
