ABSTRACT: Because
its high efficiency, its simple stator and rotor structures, the low cost and
high reliability, speed operation combined
with robust and low cost construction, the switched reluctance machines have represented. In recent years, an interesting alternative to other machine
types has been chosen for traction applications especially starter-generator.
Their rotors do not generate significant heat, resulting in easy cooling. Their unidirectional flux and current may
generate lower core losses and require a simple converter design. Moreover, the
switched reluctance machines are known for
their high reliability and capability of operating in four quadrants for a
variable speed drive. Despite those merits, switched reluctance
machine has not been extensively used until recently because of its problems of
torque ripples and noise. Additionally, researchers have faced many difficulties to build a SRM model because it
is inherently multivariable. It has strong coupling and especially a
high nonlinearity. In this paper, we deal
with many modeling methods. Numerical, analytical and intelligent approaches are studied. The important aim in this research is to use static results from
FEMM simulation as flux-linkage, co-energy, static torque to form a dynamic
model of a switched reluctance machine used next as a starter-generator of a
hybrid vehicle.
