An expression for the voltage response of a current‐excited fractance device based on fractional‐order trigonometric identities

Abstract: SUMMARYWe report a closed-form expression of the voltage response of a current-excited fractance device. The derived simple expression is made possible following the introduction of the generalized sine and cosine functions (sin (t) and cos (t)), which are valid on any fractional-order surface and tend to the normal sin(t) and cos(t) at = 1 or asymptotically as t → ∞.

“…For example, the modeling of viscoelasticity as well as of biological cells and tissues has been performed through the utilization of the fractional-order calculus. In addition, fractional-order filters and oscillators have been developed, and the offered benefits, in comparison with their integer-order counterparts, include more precise control of the attenuation gradient and boosting of the frequency of oscillation independent of the capacitance value [1][2][3][4][5][6][7][8][9].…”

“…The first operator is the derivative of the convolution of a given function and a power-law kernel, and the second one is the convolution of the local derivative of a given function with power-law function. In other studies, [26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42] authors developed electrical circuits models using FC; they used the Riemann-Liouville or Liouville-Caputo fractional-order derivative operators. The Liouville-Caputo operator is more suitable for modeling real-world problems since it allows using initial conditions.…”
