This paper proposes a control strategy capable of reducing the vibration while keeping a low torque ripple for a switched reluctance machine (SRM). The aim is to minimize the variation of the radial force and to optimize the torque control parameters. At first, the torque ripple reduction method is introduced, for which an off-line optimization of control parameters is adopted. Then, the vibration...
The inherent advantages such as high robustness, low cost and high starting torque have made switched reluctance machine a strong candidate for electric vehicle applications. However, the serious vibration and acoustic noise are very troublesome. In this paper, a semi-analytical vibration prediction model is developed and an enhanced vibration reduction method is presented via random-varying turn-off...
This paper proposes a combined modeling method for switched reluctance machine (SRM) with few samples of flux linkage characteristics measured without rotor clamping devices and position sensors. The proposed method mainly consists of two steps, namely data reconstruction and characteristic description. In data reconstruction, the entire flux linkage characteristics are obtained by training support...
