A Flat Triangular Structure Based on a Multi-Chained Form
Georg Hartl, Conrad Gstöttner, Markus Schöberl
Determining whether a nonlinear multi-input system is differentially flat remains challenging. One way to obtain computationally tractable sufficient conditions is to give complete…
Flatness of Two-Input Discrete-Time Systems and their Linearization
Johannes Schrotshamer, Bernd Kolar, Markus Schöberl
In this contribution we discuss flat discrete-time nonlinear systems in a general setting including two special subclasses, namely, forward- and backward-flat systems. We relate ra…
On Triangular Forms for x-Flat Control-Affine Systems With Two Inputs
Georg Hartl, Conrad Gstöttner, Markus Schöberl
This paper examines a broadly applicable triangular normal form for x-flat control-affine systems with two inputs. First, we show that this triangular form encompasses a wide range…
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…
