An NUTSF at Sub-Region for Suppression of Torque Ripple in Switched Reluctance Motors

open access: yesApplied Sciences, 2022
The conventional torque sharing function (TSF) control strategy in a switched reluctance motor (SRM) has higher torque ripple due to the weak torque tracking ability with an increase in speed.

Predictive Direct Torque Control for Flux and Torque Ripple Reduction [PDF]

open access: yesIEEE Transactions on Industrial Electronics, 2010
In this paper, a prediction scheme is presented to diminish both the torque and flux ripples in a direct torque control (DTC) induction motor drive. In a discrete implementation of the classical DTC scheme, the time delay associated with data processing results in additional torque and flux ripples.

A Novel Region-Refinement Pulse Width Modulation Method for Torque Ripple Reduction of Brushless DC Motors

open access: yesIEEE Access, 2019
Brushless dc motors (BLDCMs) exhibit relatively large torque ripple due to the current pulsation during the commutation process. In this paper, first, the production mechanism of the commutation torque ripple is analyzed in detail, where the diode ...

Torque prediction using the flux-MMF diagram in AC, DC, and reluctance motors [PDF]

open access: yes, 1996
This paper uses the flux-MMF diagram to compare and contrast the torque production mechanism in seven common types of electric motor. The flux-MMF diagram is a generalized version of the flux-linkage versus current (ψ-i) diagram for switched-reluctance ...

Comparative Investigation of Torque-ripple Suppression Control Strategies Based on Torque-sharing Function for Switched Reluctance Motor

open access: yesCES Transactions on Electrical Machines and Systems, 2022
Torque ripple is an inherent property of switched reluctance motor (SRM), which seriously affects the control performance and application of the motor. This paper proposes two torque ripple suppression control strategies based on torque-sharing function (
