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…
