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 one variable functions (average torque) step by step, penalties are added for improving the ripple content and eventually the efficiency. The effects of using local and global minimizers are outlined and comparative results are given. Experimental results obtained on a 0.75kW SRM are provided and 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...
A sliding mode controller to minimize SRM torque ripple and noise
Bizkevelci, E; Leblebicioğlu, Mehmet Kemal; Ertan, HB (2004-01-01)
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 appropri...
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...
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 ...
A unity power factor buck type PWM rectifier for medium/high power DC motor drive applications
Bilgin, HF; Kose, KN; Zenginobuz, G; Ermiş, Muammer; Nalcaci, E; Cadirci, I; Kose, H (2000-10-04)
This paper describes the application of a single stage unity pf buck type PWM rectifier to medium and high power variable speed dc motor drives. The advantages of the developed system are low harmonic distortion in ac supply currents (comply with IEEE Std. 519 and IEC 555), nearly unity pf over a wide operating shaft speed range, nearly level armature -current and -voltage waveforms. These properties of output voltage and current quantities of the converter eliminate entirely any failure risk in current com...
