Speed Control of SRM Drive Using Closed Loop Bridgeless SEPIC with P, PI and Fuzzy Logic Controller

1 min read


The Switched Reluctance Machine (SRM) is used for many application of electric drive system due to its simple construction and its robustness. Due to doubly salient structure of SRM; the torque pulsations are high when compared to other sinusoidal machines. The major drawback of using SRM drive is torque pulsations and increased components in the converter. In order to avoid these drawbacks a new bridgeless Single Ended Primary Inductor Converter (SEPIC) for closed loop control of SRM drive is proposed. The proposed converter reduces a conduction loss, input current ripple, torque ripples and also the Total Harmonic Distortion (THD). The requirements of converter for switched reluctance motor drives and the proposed new converter are analyzed and discussed. The torque, current, speed of SRM for the proposed converter is analysed also the speed of SRM is controlled by applying the conventional P& PI Controller and  AI based Fuzzy Logic Controller in MATLAB simulation. The results are presented for comparison with P.PI and Fuzzy logic controllers. The simulation results reveals that the new bridgeless SEPIC converter in close loop operation using fuzzy logic controller provides better results with quicker speed settling time.
