“…A switched reluctance motor (SRM) has the following advantages: rigid and simple structure, simple converter circuit with fault tolerance, high starting torque, premium speed regulation, etc. However, the SRM suffers from high ripples in the output torque due to the discrete nature of the torque production and high nonlinear characteristics that complicate the analysis as well as the control of the motor [1][2][3][4][5].…”

Saliency and nonlinear magnetization characteristics of switched reluctance motor (SRM) are causes for its poor performance regarding torque ripples. This paper presents an innovative methodology based on a water cycle algorithm (WCA) for SRM speed control with minimum torque ripples and maximum torque per ampere. WCA enhances the dynamic and steady-state performance of this motor by optimizing a multiobjective function consisting of three parts. The first part is the integral time absolute error (ITAE) of motor speed with respect to a desired reference speed, the second part is an index for a motor torque smoothness factor (TSF), and the third part is the torque per ampere ratio (TAR). The desired output of WCA is the appropriate gains of the PI speed controller and optimum turn on and off angles of the H-bridge driving circuit. The results obtained from WCA are used to construct an adaptive controller-based artificial neural network (ANN) to automatically tune the gains of the PI speed controller and the turn on and off angles. The ANN controller ensures superior steady-state and dynamic motoring operation over a wide range of speed commands and different loads. The results of WCA are verified by other well-known meta-heuristic optimized techniques, such as the Genetic algorithm (GA). The suggested method exhibits an excellent speed transient response in addition to minimum torque ripples and maximum TAR.

“…The SRM is a simple and robust motor, with flexible mechanical characteristics. A unique construction of SRM with salient rotor and stator poles without rotor winding, proves a motor as an inherent adjustable speed drive [18][19][20][21][22][23][24]. SRM is a highly reliable machine under faulty condition as the rotor does not require any sort of excitation and does not induced any power in the faulted phase.…”

“…This torque nature is because of discrete phase current. Moreover, this discrete nature of current is reduced by adopting simultaneous excitation of two phases [19][20][21][22][23][24]. Here, two SRM phases are excited simultaneously to make average phase current continuous, therefore, reducing the average torque ripple.…”

This study presents a power factor correction (PFC)-based switched reluctance motor (SRM) drive, as a best selection for low-voltage household applications. Here, a Cuk converter fed SRM drive is proposed for power quality improvement and complete motor control. The operation of Cuk converter is explained under three modes, with associated voltage and current waveforms during energy transfer between circuit components. The converter is designed to operate in discontinuous conduction mode (DCM) to obtain inherent PFC. However, DCM offers zero current switching on and no reverse recovery in a diode. The wide range of DC-link voltage is obtained with an improved power quality at supply side by controlled switching of the Cuk converter. The analysis of an inductor current waveform is presented to demonstrate inherent PFC technique in DCM. The power quality indices are measured on power quality analyser to demonstrate the test results. The obtained experimental results validate the stable drive performance under dynamic and steady state conditions.

This research introduces a novel magnetically isolated phase structure for switched reluctance motor, namely, as Septi-Segment SRM (SSSRM), which is proper for high torque/volume and with lowest leakage flux in different fields of industries. The SSSRM contains seven stator layers that are isolated from each other magnetically, also each of them include an assembly of 4/4 stator/rotor poles. The three layers are energized at the same time for generating higher torque with lower ripple compared with the typical SRM. Furthermore, this configuration results other advantages, such as easy cooling and independent phases. To evaluate the proposed motor performance, the configuration is introduced at first. Secondly, the motor profiles as flux linkage, flux density, self/mutual inductance and motor torque are assessed using a 3D finite element method (3D-FEM). An SSSRM has been manufactured with a test bench in the laboratory, and the experimental results of the new motor and typical type were compared in the same volume and area. The results and comparative study clearly demonstrate the prominent features of the proposed motor for various applications.
