A matched space for time scales and applications to the study on functions

Advances in Difference Equations, 2017
In this paper, using the algebraic structure of the Abelian group, we introduce the concept of a matched space for time scales, and we construct the algebraic structure of matched spaces to solve the closedness of time scales under non-translational ...

Analysis of servo-constraint problems for underactuated multibody systems [PDF]

Mechanical Sciences, 2013
Underactuated multibody systems have fewer control inputs than degrees of freedom. In trajectory tracking control of such systems an accurate and efficient feedforward control is often necessary.
