Torque ripple minimization of the of 6/4 switched reluctance motor with speed controller

Basically switched reluctance motor (SRM) is associated with torque ripple and acoustic noise. So, with control of torque ripple, SRM performance can be enhanced. The torque control is achieved with speed control. This paper designed the speed controller and fed to switched reluctance motor (SRM) with two converter topologies i.e. C-Dump converter and R-dump converter to minimize the torque ripples using MATLAB Simulink. The 6/4 SRM motor speed is compared with reference speed and speed error signal is processed through speed controller to produce the current command signal. This current command signal is given to SRM phase, there it again compare with phase current and generate the current error signal. The switching signal for SRM is generated with this current error signal. Simulation results shown for two converter topologies. Simulation results shows, performance of speed controller is similar to conventional PI controller with minimum torque ripple.
