Performance simulation of a switched reluctance motor using Matlab / Adrian Buayeh Tadam

This paper presents a simulation program for switched reluctance motor (SRM) using Matlab. The program is intended to be used a reference program for comparing with other approximate modeling techniques. Due to the non-linear magnetic characteristics of SR motor, there is no closed-form relation available for predicting the current and torque of this type of motor. The usual approach is to employ a model based on extensive non-linear flux-linkage/current ('P-t) data at various rotor positions 0 obtained either by measurement or finite element analysis. The current at the other 'P-0 positions is obtained either by splice or polynomial interpolation. This type of model has generally been considered as the benchmark model in recent years. Since this model requires extensive and expensive data, it is always appropriate for routine design analysis. However, it can be valuable in verifying a final design prototype. Based on the developed simulation program, simulation studies are performed and compared to measure motor phase current either for hysteresis or voltage control strategies to validate the program.
