Introduction. Switched reluctance motor (SRM) is a type of electric featuring nonlinear magnetic characteristics. The flux linkage or inductance profile SRM usually required for the purpose high control performance, and can be normally obtained through conventional static test by using DC AC method when rotor locked.

One challenge to predict output performance characteristics of switched reluctance machines (SRM) is the accurate estimation of the minimum inductance of the stator phase at unaligned position of the rotor.

This paper presents the speed control of SRM which is directly fed from an AC supply through a simple R dump converter. The controller uses fuzzy logic control (FLC) for switched reluctance motor (SRM) speed. The FLC performs a PI-like control strategy, giving the current reference variation based on speed error and its change. The performance of the drive system was evaluated through digital s...

This study presents a novel Switched Reluctance Motor (SRM) drive system with power factor improvement. Recently, many of the converters with variable speed drives have no input power factor correction circuits. This results in harmonic pollution of the utility supply, which should be avoided. The effect of power factor variation in terms of harmonic content is also analyzed in this study. The ...

A novel control approach to design efficient speed controllers for Switched Reluctance Motor (SRM) drives based on fuzzy logic (FL) and Particle Swarm Optimization (PSO) techniques is investigated in this study. The PSO mechanism with the simple implementation and high efficiency is adopted to optimize five parameters, including three scaling factors of a PI-like FL architecture and two switchi...

In this paper modelling and analysis of the SRM torque characteristics including torque ripples are described. Optimal control strategy based on genetic algorithm (GA) to minimize torque ripple is proposed. The optimization criteria depend on choosing the exact current profile based on the optimal excitation parameters which govern the torque shape. The model and control are carried out on high...
