Pseudotransient Continuation and Differential-Algebraic Equations [PDF]

open access: yesSIAM Journal on Scientific Computing, 2003
The authors present a globally convergent method for semi-explicit index-1 differential-algebraic equations (DAEs) given by an iteration procedure. Pseudotransient continuation is a practical technique for globalizing the computation of steady-state solutions of nonlinear differential equations and is applied here to DAEs.

Symbolic Analysis for Boundary Problems: From Rewriting to Parametrized Groebner Bases [PDF]

open access: yes, 2010
We review our algebraic framework for linear boundary problems (concentrating on ordinary differential equations). Its starting point is an appropriate algebraization of the domain of functions, which we have named integro-differential algebras.

Numerical Solution via Operational Matrix for Solving Prabhakar Fractional Differential Equations

open access: yesJournal of Mathematics, 2022
In this work, we apply the operational matrix based on shifted Legendre polynomials for solving Prabhakar fractional differential equations. The Prabhakar derivative is defined in three-parameter Mittag-Leffler function. We achieve this by first deriving

Modeling and PDC fuzzy control of planar parallel robot

open access: yesInternational Journal of Advanced Robotic Systems, 2017
Many works in the literature have studied the kinematical and dynamical issues of parallel robots. But it is still difficult to extend the vast control strategies to parallel mechanisms due to the complexity of the model-based control. This complexity is
