Abstract: At the present time an important tendency in industrial automated systems is to
apply equipments that can assure uninterrupted operation even if a fault occurs. Advanced
electrical drives are complex systems containing both hardware and software. In order to obtain a
reliable electrical drive system all its major components have to be fault tolerant. In this paper two
switched reluctance machines are studied in order to compare their fault tolerance capability at
different stator winding faults.
Keywords: Fault tolerance, Switched reluctance machine, Coupled simulation
The concept of fault tolerance emerged in the field of information technology (IT)
because of the demand of safety and reliability of a system. Later in more and more
fields of engineers tried to design fault tolerant complex systems .
A system is the interconnection of components connected together for achieving the
same goal: to assure a certain output for a given application. As errors are part of life,
the possibility of their appearance in a system must be taken into consideration.
Nevertheless, fault tolerant systems are not easy to achieve. A fault tolerant system
must detect faults in its components and also must have the ability either to correct it
(for example by switching to a backup unit when the main one fails) or to circumvent it
(by reconfiguring the system) .
