“…These efforts have led to significant improvements in the performance and reliability of the SRM, making it an attractive option for various applications. (Han et al 2019(Han et al , 2021Xu et al 2019Xu et al , 2022Ferková et al 2020;Nandu Krishnan et al 2020;Fang et al 2021;Sun et al 2021;Kotb et al 2022) However, to fully utilize the advantages of SRMs, it is important to have effective control methods that can accurately regulate the motor's torque and speed. There are several methods of controlling SRMs, each with its own advantages and disadvantages.…”

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 DTC, the switching signal of the power converter is directly generated by combining the error between the command torque and the instantaneous torque of SRM with the appropriate commutation logic [8][9][10]. e instantaneous torque of the SRM is usually calculated from the measured rotor position and phase current [11]. DTC has the advantage of simple structure and easy implementation because it has no current loop [12].…”

This paper proposes a high-performance indirect control scheme for torque ripple minimization in the switched reluctance motor (SRM) drive system. Firstly, based on the nonlinear torque-angle characteristic of SRM, a novel torque sharing function is developed to obtain the optimal current profiles such that the torque ripple is minimized with reduced copper losses. Secondly, in order to track current accurately and indirectly achieve high-performance torque control, a robust current controller is derived through the Lyapunov stability theory. The proposed robust current controller not only considers the motor parameter modeling errors but also realizes the fixed frequency current control by introducing the pulse width modulation method. Further, a disturbance-observer-based speed controller is derived to regulate the motor speed accurately, and the load torque is considered an unknown disturbance. The simulations and experiments on a 1.5 kW SRM prototype are carried out to demonstrate the effectiveness of the proposed high-performance indirect torque control strategy. Results verify the superiority of the proposed strategy with respect to the torque ripple suppression, system efficiency, and antidisturbance.

“…The bilateral salient pole VRM is more popular due to its many advantages, such as the largest ratio of maximum to minimum reluctance and better electromechanical energy conversion characteristics. There are three types of EEDSVRM, namely the Wound-field Doubly Salient Machine (WFDSM) [3], Switched Reluctance Machine (SRM) [4], and Electrical Excitation Flux-switching Machine (EEFSM) [5], as shown in Figure 1.

The Electrically Excited Doubly Salient Variable Reluctance Machine (EEDSVRM) is a new type of brushless machine designed according to the principle of air gap reluctance change. There is neither permanent magnet steel nor excitation winding on the rotor. The rotor is made of silicon steel sheets, thus the structure of the variable reluctance machine is very simple. There are many optimization methods for this type of machine optimal design, such as novel machine topology optimization, finite element simulation-based optimization, mathematical analysis-based optimization, intelligent algorithm-based optimization, and multiple fusion-based optimization. Firstly, this article introduces the basic structure and working principle of the EEDSVRM and analyzes both its common regularity and individual difference. Then, the different optimization design methods of EEDSVRM are reviewed, the advantages and disadvantages of the different optimization methods are summarized, and the research interests of the optimization design of variable reluctance machines in the future are prospected.
