“…integrated configuration, low cost, high torque density, efficient power transfer, and direct drivetrain system, has become a promising choice for in-wheel motors (IWMs) applications [4], [5]. However, IWSRM also suffers from high torque ripple and unbalanced radial force caused by a great nonlinear step-by-step magnetic field [6]- [8]. The resultant vibration from IWSRM will greatly influence the drive and comfort performance of EVs.…”

The in-wheel switched reluctance motor (IWSRM) has significant potential for utilization in electric vehicle (EV) because of its inherent advantages such as low cost, robustness, wide speed range, and direct drive mode. However, the unbalanced radial force caused by eccentricity of IWSRM results in increasing vehicle vibration and decreasing riding comfort. In this paper, various vertical vibration control strategies for IWSRM are proposed and compared to improve the vibratory behavior of vehicle. First, effects of eccentricity ratio and eccentric angle on radial force, torque, and inductance are investigated by numerical analysis method for IWSRM. Then, IWSRM model, vehicle model, and suspension model are developed, based on which two common control algorithms (i.e. CCC and PWM) are provided and used as benchmarks to compare with the newly proposed two (i.e. CCC-F and PWM-F). They are designed by introducing the vehicle vertical acceleration as an extra control objective. Finally, the dynamic response of four control strategies are analyzed and the comparison results show that each of them performs differently under different driving conditions. As a result, a switchable controller based on the proposed control algorithms is presented to improve the overall performance of the IWSRM for EVs under various driving modes.

“…Another study by (Zhang et al 2019) DFTC presents a control strategy for a switching reluctance motor (SRM) to reduce vibration and minimize torque ripple by optimizing torque control settings and reducing radial force variance. The strategy includes offline control parameter modification and the use of Direct Force Control (DFC) to lower total radial force variations.…”

The following study is concerned with the controlling and optimization of a switch reluctance machine (SRM) efficiency by a new method proposed for control. The direct force and energy control DEFC, a new method proposed in this work, is based on the direct torque control (DTC), thus in this control, it is directly controlled the energy and the force the simultaneously. This control aims to increase the efficiency of the SR motor and reduce the torque ripple and vibration of the motor. in this work, we applied three methods of control and the proposed method for controlling the switch reluctance motor, including the one that was suggested. in order to prove the efficiency of DEFC we compare the simulation result of it with the result of DEC, DFC, and conventional DTC strategies. We deduced from the findings that the suggested technique DEFC performed better than the other ways and reduced the torque ripple to 10 percent, which enhances the performance of the SRM.

In order to improve the reliability in torque calculation of SRM, an accurate nonlinear torque model regresses by recursive robust least squares support vector regression (RR-LSSVR) is proposed in this paper. The model is in terms of a segmented-rotor switched reluctance motor (SSRM). The characteristics of the SSRM is introduced to show its nonlinear characteristics both in magnetic and torque. Then, its mathematic model is established, and an accurate inductance measurement method and a torque calculation method are presented. After this, the principle of the RR-LSSVR and why it can adjust weights according to errors are described. The model used the RR-LSSVR algorithm shows an outstanding capability in accuracy and quickness compared with other algorithms. Finally, to further validate the accuracy of the proposed model in practical application, simulation and experiment are designed based on a 16/10 SSRM.
