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.

“…Switched reluctance motor (SRM) was first proposed in the 1840s, but was not developed very well due to the technical limits at that time. With the development of power electronic devices as well as SRM's advantages such as simple structure, low cost, good fault tolerance and wide speed range, it has aroused extensive attention from the academic and industrial circles, and a great deal of research has been carried out [1][2][3][4]. The SRM speed control systems of various specifications are also put into the market.…”

Since the traditional direct torque control (DTC) of switched reluctance motors (SRMs) has the shortcomings of large torque ripple and non-constant switching frequency, this study proposes the deadbeat-direct torque and flux-linkage control (DB-DTFC) method for SRM. By analysing the basic principles of SRM, a discrete-time model is established to predict the future states of the SRM drive system. With DB-DTFC, the stator flux and torque can be manipulated during each pulse-width modulation cycle to minimise torque ripple during operation. As a result, the proposed DB-DTFC can minimise the torque ripple as well as apply space-vector modulation with a constant switching frequency. Finally, to verify its effectiveness, DB-DTFC was applied to the 15 kW three-phase 12/8-pole SRM test bench in real time and the results are compared with conventional DTC.

“…On the other hand, CVS using PWM scheme is not often used, despite of its many advantages. However, using the modeling and control theory proposed by the authors [4,5], CVS with PWM scheme could be easily applied to SRMs. Thus, in this paper, we propose a current control method for SRMs using CVS with PWM scheme.…”

SUMMARY This paper proposes controlled voltage source vector control for switched reluctance motors using the pulse width modulation method. This proposed technique can achieve high controllability for variable speed drives, low current ripple and low noise operation, and high motor efficiency at high speed. Moreover, its implementation is easy because the controller design does not require complicated offline data such as the magnetization characteristics. To verify the effectiveness, an experiment was conducted to compare the performances of the proposed technique and a conventional unipolar drive using the hysteresis comparator method.
