Discrete-time Flatness and Linearization along Trajectories
Bernd Kolar, Johannes Diwold, Conrad Gstöttner +1
The paper studies the relation between a nonlinear time-varying flat discrete-time system and the corresponding linear time-varying systems which are obtained by a linearization al…
Flatness Analysis for the Sampled-data Model of a Single Mast Stacker Crane
Johannes Diwold, Bernd Kolar, Markus Schöberl
We show that the Euler-discretization of the nonlinear continuous-time model of a single mast stacker crane is flat. The construction of the flat output is based on a transformatio…
A Flat System Possessing no (x,u)-Flat Output
Conrad Gstöttner, Bernd Kolar, Markus Schöberl
In general, flat outputs of a nonlinear system may depend on the system's state and input as well as on an arbitrary number of time derivatives of the latter. If a flat output whic…
Discrete-time Flatness-based Controller Design using an Implicit Euler-discretization
Johannes Diwold, Bernd Kolar, Markus Schöberl
In this contribution, we present a constructive method to derive flat sampled-data models for continuous-time flat systems through an implicit Euler-discretization. We show how the…
On the Exact Linearization and Control of Flat Discrete-time Systems
Bernd Kolar, Johannes Diwold, Conrad Gstöttner +1
The paper addresses the exact linearization of flat nonlinear discrete-time systems by generalized static or dynamic feedbacks which may also depend on forward-shifts of the new in…
