Some considerations on torque ripple suppression in reluctance motors

open access: yesElectrical Engineering in Japan, 1998
Although the reluctance motors are attractive from the standpoints of simple construction and drive electronics, the relatively high torque ripple and acoustic noise are the major drawbacks. These drawbacks make the motor application limited.In the paper, the torque ripple suppression of the reluctance motor under the sinusoidal current drive is ...

Torque Ripple Suppression for IPMSM using FEA- based Model Predictive Direct Torque Control [PDF]

open access: yes2021 IEEE Workshop on Electrical Machines Design, Control and Diagnosis (WEMDCD), 2021
The interest in model predictive direct torque control (MP-DTC) for high-performance dynamic control of electric drives has been growing. Unlike the conventional direct torque control (DTC), MP-DTC can achieve optimal voltage selection by predicting the control variables evaluations using a machine model. However, the model-machine mismatch can degrade
