Collocation Methods for Second Order Systems

open access: yesRobotics: Science and Systems XVIII, 2022
Collocation methods for numerical optimal control commonly assume that the system dynamics is expressed as a first order ODE of the form x¿ = f(x, u, t), where x is the state and u the control vector. However, in many systems in robotics, the dynamics adopts the second order form q¨ = g(q, q¿, u, t), where q is the configuration.

Studies on the Method of Orthogonal Collocation VII: An Efficient Collocation Method for Diffusion-convection Problems with Chemical Reaction

open access: yesJournal of King Saud University: Engineering Sciences, 2008
In this work we present a new numerical scheme based on orthogonal collocation method to solve a reacting flow problem. The method is based on recasting the problem to become a larger set of first order differential equations and we show by numerical ...

On $hp$-Convergence of PSWFs and A New Well-Conditioned Prolate-Collocation Scheme

open access: yes, 2013
The first purpose of this paper is to provide a rigorous proof for the nonconvergence of $h$-refinement in $hp$-approximation by the PSWFs, a surprising convergence property that was first observed by Boyd et al [J. Sci. Comput., 2013].
