This paper is an attempt to eliminate the torque pulsation of switched reluctance (SR) motors. It is well known that pulsed radial and tangential forces are the source of acoustic noise problems often mentioned in relation to SR motors. In this study, to control the force pulsations, phase voltage is selected as the control variable contrary to what is often encountered in the literature. The authors believe that cost effective implementation of this choice is now technically possible. Selection of appropriate phase voltages is achieved by Sliding Mode Control in order to produce the pre-defined torque references for each phase. The paper first illustrates via simulations that such an approach effectively eliminates the torque ripple and follows the defined reference, if the derivative of error function is appropriately chosen. The performance of the motor with different choice of Sliding Mode functions is given. The performance of the final choice is also experimentally illustrated. Various application issues of this type of controller are discussed.

A Novel Noise Reduction Technology for Switched Reluctance Motors
Bizkevelci, Erdal; Özlü Ertan, Hatice Gülçin; Leblebicioğlu, Mehmet Kemal (2008-07-24)
The conditions are sought at which an SIR motor can be operated with highest efficiency, while producing a desired torque output at low shaft torque ripple. The investigation is based on the simulation software that uses measured flux-linkage (V, 0, 1) and static torque (T, 0, 1) characteristics of a given motor. The variation of the shaft torque, torque ripple and efficiency of the motor Is investigated, while the control variables "advance angle" and "conduction angle" are swept over their range with a co...
Direct Torque Control of a 4-Phase Switched Reluctance Machine
Petrus, V.; Pop, A. -C.; Martis, C. S.; Iancu, V.; Gyselinck, J. (2011-09-10)
Due to its doubly salient structure and highly nonlinear behavior, the Switched Reluctance Machine (SRM) operates with very high torque ripple. To overcome these inconveniences different average and instantaneous torque control techniques were developed. This paper presents an instantaneous torque control technique named Direct Torque Control (DTC) implemented on a 4-phase, 8/6, 0.75kW SRM. Simulations results with modified flux observer and with fast torque response are presented and discussed, along with ...
Wide-Speed Range Control Strategy for a 8/6 Switched Reluctance Machine
Pop, A. C.; Petrus, V.; Martis, C. S.; Iancu, V.; Gyselinck, J. (2011-09-10)
A control scheme for obtaining low torque ripple and high efficiency for a minimal reduction in average torque as compared to its maximal value is presented for a four-phase switched reluctance motor. At low speed, the torque ripple is minimized by the means of current profiling techniques. As the speed increases the controller switches to optimal firing angle control strategy. The optimal values for the angles are obtained based on minimization routine for different objective functions. Starting from the o...
An analytical approach for determination of optimal stator/rotor saliency number of a swıtched reluctance motor
Kılınç, Cem Erkan; Bostancı, Emine; Department of Electrical and Electronics Engineering (2020)
The purpose of this study is to seek the optimal stator and rotor saliency number of a switched reluctance motor (SRM) for hybrid electrical vehicle (HEV) applications. For this purpose, first a previously developed SRM analysis software is investigated to identify possible errors in implementation of both the theory and the coding. Performance prediction method is based on the use of normalized force and permeance data produced via numerical field solution, and a polynomial based interpolation is introduce...
Effects of control parameters on SRM performance: A parametric search
Bizkevelci, E.; Özlü Ertan, Hatice Gülçin; Leblebicioğlu, Mehmet Kemal (2007-09-12)
This paper investigates the effects of the SRM control parameters on torque ripple and efficiency. The average shaft torque, torque ripple and the torque per ampere variation of the motor are observed at different turn-on and conduction angles. The study is performed using simulation software developed by the authors. Some experimental results are presented which indicate that the software promises to be accurate. The findings of the study are presented to give an idea about the optimum switching strategy t...
