OCTSF for torque ripple minimisation in SRMs
IET Power Electronics, 2016 In this study, a new online compensation of torque sharing function (OCTSF) method is proposed to minimise the torque ripple in switched reluctance motors (SRMs). For SRMs, the torque ripple is a serious issue which is mainly produced by the overlapped conduction phases in the commutation region.

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

Torque ripple minimization of a switched reluctance motor [PDF]
Proceedings of 1995 IEEE Applied Power Electronics Conference and Exposition - APEC'95, 1995 This paper presents a simple technique to minimize torque ripple of a switched reluctance motor. The technique is based on the control of the sum of the square of the phase currents by using only two current sensors and analog multipliers. The simulation results and a proposed circuit are given.

Optimization of torque ripples in direct torque control drives
Proceedings of the Russian higher school Academy of sciences, 2021 The article discusses the features of the synthesis of a hybrid method for commutation of a three-phase inverter in a classic version of drives with direct torque control (DTC), which involves the use of relay characteristics in the flux- and torque control blocks.

Improved Direct Torque Control of Induction Motor for Torque Ripple Minimization
IEEE Access, 2022 A new direct torque control (DTC) method of an induction motor (IM) which minimizes torque ripple $\left ({T_{ripp} }\right)$ while preserving all the conventional DTC advantages is presented in this paper. Large $T_{ripp}$ and current ripple are the main drawbacks of the conventional DTC.
