Abstract :
The concept of fractional-order control (FOC) means controlled systems and/or controllers are described by fractional-order differential equations. Expanding derivatives and integrals to fractional orders is by no means new and actually has a firm and long-standing theoretical foundation. The paper discusses the three main advantages for introducing fractional-order calculus to control control engineering.
