“…A method by injecting harmonics current into DC current component is proposed to reduce the torque ripple of variable reluctance motor [12,13]. In [14], the 3rd harmonic current injection is also applied to reduce torque ripple of SRM. Although these above harmonic injection methods can reduce partial torque ripple, magnetic saturation is not considered.…”

To reduce torque ripple of switched reluctance motor (SRM), a low-torque ripple control method based on current vector is proposed in this study. In which, i d = 0 control strategy is adopted. Then, i q is decomposed into the vector sum of twophase currents in different positions. A Fourier series model about T e and i q is established and this model satisfies the magnetic saturation condition. According to the established Fourier series model, the change rule of i q based on constant reference torque is obtained. In this study, torque models of SRM under traditional unipolar sinusoidal excitation control method, constant i q unipolar excitation control method and variable i q unipolar excitation control method are analysed. Finally, experimental platform of SRM control system based on TMS320F2812 is built. Experimental results show that the variable i q unipolar excitation method based on current vector decomposition can effectively reduce the torque ripple of SRM.

This paper proposes a novel deadbeat torque and flux control (DB-DTFC) to reduce torque ripple for switched reluctance motor (SRM). DB-DTFC combines the advantages of direct torque control (DTC) and space-vector modulation (SVM). DB-DTFC leads current vector control into DTC in order to find the equation between torque and current through deadbeat prediction theory i.e. a beat reaches a given point. In addition, the deadbeat calculation module here is similar to that of permanent magnet synchronous motor. Based on dq0 reference frame of SRM, the most suitable dq0 axis current of next moment corresponding to different torque errors is calculated and predicted. According to the calculated dq0 axis current, the optimal space voltage vectors can be selected to reduce torque ripple. In order to verify the effectiveness and correctness of the proposed scheme, DB-DTFC is verified and compared with the DTC-SVM by simulation.

“…The associate editor coordinating the review of this manuscript and approving it for publication was Xiaodong Liang . In the past decade, vibration suppression of IWSRM itself has been studied by various methods, including structure optimization [9]- [11], power converter design [12], [13], and control strategies [7], [8], [14], [15]. However, differing from the centralized SRM drive system, IWSRM is coupled with vehicle suspension.…”

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.
