A novel current controller for constant current injection based characterization of switched reluctance machine (SRM) is proposed here. Unlike conventional characterization methods, where the rotor is locked at a fixed position, the current injection based method maintains the phase current constant while the machine is run at constant speed. The proposed constant current injection scheme yields the...
Switched reluctance machine drive requires knowledge of flux linkage characteristics and its partial derivatives for high performance controller design and implementation. A mathematical model, which accurately describes the flux linkage characteristics as well as easily provides its partial derivatives, is proposed in this paper. The proposed model, even though accurate, has fewer parameters than...
Proportional Integral (PI) controller based current control is widely employed in differenct motor drives. However, in case of switched reluctance motor (SRM), the non-linearity and double wsaliency of the motor make the modelling and controller design challenging. This paper attempts linearisation of the flux linkage characteristic of the SRM at different operating points. The models include saturation...
