Torque ripple reduction of permanent magnet synchronous motors based on predictive sequence control

To reduce the torque ripples of permanent magnet synchronous motor, this paper proposes a predictive sequence control (PSC) algorithm. Comparing with conventional predictive torque control, PSC takes different switching sequences applied to synthesize voltage vectors into account, and the switching sequence that produces minimum torque ripples will be selected by corresponding predictive algorithm. Therefore, the proposed PSC will achieve excellent torque performance.
