Torque Ripple Suppression of Permanent Magnet Synchronous Motor Based on Resonance Active Disturbance Rejection Control

To suppress the torque ripple of permanent magnet synchronous motor (PMSM), a torque ripple suppression control strategy of PMSM Based on resonance active disturbance rejection control (RADRC) is proposed in this paper. On the basis of the traditional linear extended state observer (LESO), a sinusoidal disturbance estimator (SIE) is added, which can well estimate the 6th harmonic of the electromagnetic torque. Finally, a simulation model is established to verify the effect of RADRC on torque harmonic suppression.
