The latest investigations in SCs use Fuzzy or neuro-fuzzy algorithms in the optimization algorithm, instead the
traditional search algorithms such as: Rosenbrock method, Fibonacci, Golden section, Gradient, Proportional method.
The use of fuzzy logic in SCs (FLSCs) the recent years indicates by experience that these controllers can perform
high performance in motor drives applications, that they provide high degree of accuracy without the need of detailed
mathematical models, that they can be cost effectively implemented and that they allow rapid implementation of
complex fuzzy logic controllers (FLCs) into low-cost modern digital signal processors (DSPs) [5].
