Indirect methods of collocation: Trefftz‐Herrera collocation
Numerical Methods for Partial Differential Equations, 1999Summary: A nonstandard collocation method (TH-collocation) is presented, where collocation is used to construct specialized weighting functions instead of the solution itself, as it is usual, so that in this sense it is an indirect method. TH-collocation is shown to be as accurate as standard collocation, but computationally far more efficient.

Collocation and Relaxed Collocation for the Fer and the Magnus Expansions
SIAM Journal on Numerical Analysis, 1999This paper investigates the nonlinear matrix Lie-group ordinary differential equation \(y'=\gamma(t,y)y\), \(y(0)=y_{0},\) where \(y\) lies in a matrix Lie group and \(\gamma(t,y)\) is in its Lie algebra. Using the Fer and the Magnus expansions, Lie-group invariant methods based on collocation are constructed. It is proved that, provided the expansions

Proper treatment of collocations constitutes a serious challenge for NLP systems in general. This paper describes how Fips, a "Principle and Parameters" grammar-based parser developed at LATL handles multi-word expressions. In order to get more precise and more reliable collocation data, the Fips parser is used to extract collocations from large text ...

Collocated and non-collocated control
2017This chapter presents closed-loop collocated and non-collocated control approaches for flexible manipulator systems. A closed-loop control strategy using hub angle and hub velocity feedback for rigid-body motion control and end-point acceleration feedback for flexural motion control is considered.
