Analogue Implementation of a Fractional-Order PI^{\lambda} Controller for DC Motor Speed Control 

Herencsár, Norbert; Kartci, Aslihan; Koton, Jaroslav; Šotner, Roman; Alagoz, Baris Baykant; Yeroglu, Celaleddin (IEEE, 2019-06-12)
In this paper, an approach to design a fractional-order integral operator s(lambda) where -1 < lambda <0, using an analogue technique, is presented. The integrator with a constant phase angle -80.1 degree (i.e. order lambda ...

Power functions and essentials of fractional calculus on isolated time scales 

Kisela, Tomáš (Springer, 2013-08-23)
This paper concerns with a recently suggested axiomatic definition of power functions on a general time scale and its consequences to fractional calculus. Besides a discussion of existence and uniqueness of such functions, ...
