A Method to Determine the Torque Ripple Harmonic Reduction in Skewed Synchronous Reluctance Machines
In this paper, a discrete skew methodology is presented to understand the effect of skewing angle on electromagnetic torque in SynRM design. A new approach is proposed to estimate the amplitude of each torque ripple component as a function of skewing ...

Improved Direct Torque Control of Induction Motor for Torque Ripple Minimization
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.
