In the final twenty years fractional differential equations were used extra usually in physics, sign processing, fluid mechanics, viscoelasticity, mathematical biology, electro chemistry and so on. It opens a brand new and extra real looking technique to trap reminiscence established phenomena and irregularities contained in the platforms by utilizing extra subtle mathematical analysis.

This monograph is predicated at the authors’ paintings on stabilization and keep watch over layout for non-stop and discrete fractional order platforms. The preliminary chapters and a few components of the 3rd bankruptcy are written in educational model, proposing the entire easy innovations of fractional order method and a quick review of sliding mode regulate of fractional order structures. the opposite components comprise care for powerful finite time balance of fractional order platforms, vital sliding mode keep an eye on of fractional order structures, co-operative keep an eye on of multi-agent platforms modeled as fractional differential equation, strong stabilization of discrete fractional order structures, excessive functionality keep an eye on utilizing tender variable constitution regulate and contraction research through integer and fractional order infinitesimal variations.

61) can be rewritten using the notation of continued functions as f3 f2 f1 f0 V (s) =1+ . 62) following circuit was constructed by Oldham and Spanier [14], as shown in Fig. 12. Using Fig. 12, one can write f 2n−1 f 2n−2 f 2n−3 f2 f1 f0 V (s) =1+ ··· . Rn I (s) s+ 1+ s+ 1+ s+ 1 1 where f 2 j = R j1C j and f 2 j+1 = R j+1 C j for j = 0, 1, . . , n − 1. 63), one can write V (s) η2n−1 η2n−2 η2n−3 η2 η1 η0 =1+ ··· . 64) Consider the following special case for the capacitors and resistors in Fig. 12 • C0 = C1 = C2 = · · · = Cn−1 := C • R0 = R1 = R2 = · · · = Rn−1 := R and Rn := Thus 1 • η0 = η1 = η2 = · · · = η2n−2 = := η RCs 2 = 2η.

10) after t ≥ 0 and assume that current through R0 is i 0 and voltage across the capacitor is v0 (t). 52) and i(t) − i 0 (t) = C0 dv0 (t) . 53) Using Ohm’s law it is obvious that i(t) = v(t) − v0 (t) . 54) (R0 + R1 )i(t) + R0 R1 C0 di(t) dv(t) = v(t) + R0 C0 . 55) 18 1 Essence of Fractional Order Calculus, Physical Interpretation and Applications R2 R1 i 1 (t) i 0 (t) i(t) v (t) v1 C0 C1 i 1 (t) i(t) v0 R0 i 0 (t) Fig. 56) where I (s) = L {i(t)} and V (s) = L {v(t)}. 56) can be written as 1 V (s) R1 C 0 .

Possibly the one of the easiest accesses to the idea of the non-integer differential and integral operators studied in the field of fractional calculus is given by Cauchy in this well known representation of an n-fold integral as a convolution integral. 1 The n-fold integral of the function f (t) is given as t n 0 It f (t) = 0 (t − τ )n−1 f (τ )dτ, (n − 1)! 1) where N represents the set of positive integers. Proof Consider an antiderivative of the function f (t), represented as 0 It1 f (t), then one can write t 1 0 It f (t) = f (x)d x.
