A Dual Geometric Test for Forward-Flatness
Bernd Kolar, Johannes Schrotshamer, Markus Schöberl
Forward-flatness is a generalization of static feedback linearizability and a special case of a more general flatness concept for discrete-time systems. Recently, it has been shown…
A Triangular Normal Form for x-Flat Control-Affine Two-Input Systems
Conrad Gstöttner, Bernd Kolar, Markus Schöberl
This paper is devoted to normal forms for x-flat control-affine systems with two inputs. We propose a general triangular normal form which contains several other normal forms discu…
On the Exact Linearization of Minimally Underactuated Configuration Flat Lagrangian Systems in Generalized State Representation
Georg Hartl, Conrad Gstöttner, Bernd Kolar +1
In this paper, we examine the exact linearization of configuration flat Lagrangian control systems in generalized state representation with p degrees of freedom and p-1 control inp…
Exact Linearization of Minimally Underactuated Configuration Flat Lagrangian Control Systems by Quasi-Static Feedback of Classical States
Georg Hartl, Conrad Gstöttner, Bernd Kolar +1
We study the exact linearization of configuration flat Lagrangian control systems with p degrees of freedom and p-1 inputs by quasi-static feedback of classical states. First, we p…
