In this article, we survey the asymptotic stability analysis of fractional differential systems with the Prabhakar fractional derivatives. We present the stability regions for these types of fractional differential systems. A brief comparison with the stability aspects of fractional differential systems in the sense of Riemann-Liouville fractional derivatives is also given.
An adaptive memory method for accurate and efficient computation of the Caputo fractional derivative
Abstract A fractional derivative is a temporally nonlocal operation which computationally intensive due to inclusion of the accumulated contribution function values at past times. In order lessen computational load while maintaining accuracy derivative, novel numerical method for Caputo proposed. The present adaptive memory significantly reduces requirement storing time points and also improves...
in this paper, under appropriate oscillating behaviours of the nonlinear term, we prove some multiplicity results for a class of nonlinear fractional equations. these problems have a variational structure and we find three solutions for them by exploiting an abstract result for smooth functionals defined on a reflexive banach space. to make the nonlinear methods work, some careful analysis of t...
in this paper we apply hybrid functions of general block-pulse functions and legendre polynomials for solving linear and nonlinear multi-order fractional differential equations (fdes). our approach is based on incorporating operational matrices of fdes with hybrid functions that reduces the fdes problems to the solution of algebraic systems. error estimate that verifies a converge...
in this paper, a new numerical method for solving fractional optimal control problems (focps) is presented. the fractional derivative in the dynamic system is described in the caputo sense. the method is based upon biorthogonal cubic hermite spline multiwavelets approxima-tions. the properties of biorthogonal multiwavelets are first given. the operational matrix of fractional riemann-lioville i...
