For the model predictive control process of permanent magnet synchronous motors (PMSM) in the limit of low switching frequency, the low harmonics in the motor stator current have a detrimental effect on the PMSM drive system. Therefore, it is necessary to reduce the percentage of specific low harmonics under the above control method. In this paper, a model predictive specific harmonic reduction control (MPSHRC) method based on the dq axes currents is proposed, which is significant for 5th and 7th harmonic reduction at low switching frequencies.
