Control design for a class of nonlinear convection-reaction systems with storage effects and relative degree one

Jens Wurm, Frank Woittennek

This article addresses the control design for systems of several convection-reaction equations distributively coupled to a reaction equation. In typical applications, input and out…

On the controller form for linear hyperbolic MIMO systems with dynamic boundary conditions

Stefan Ecklebe, Frank Woittennek

This contribution develops an algebraic approach to obtain a controller form for a class of linear hyperbolic MIMO systems, bidirectionally coupled with a linear ODE system at the…

Calculation of time-optimal motion primitives for systems exhibiting oscillatory internal dynamics

Thomas Auer, Frank Woittennek

An algorithm for planning near time-optimal trajectories for systems with an oscillatory internal dynamics has been developed in previous work. It is based on assembling a complete…

On trajectory design from motion primitives for near time-optimal transitions for systems with oscillating internal dynamics

Thomas Auer, Frank Woittennek

An efficient approach to compute near time-optimal trajectories for linear kinematic systems with oscillatory internal dynamics is presented. Thereby, kinematic constraints with re…

Control of distributed-parameter systems using normal forms: An introduction

Nicole Gehring, Abdurrahman Irscheid, Joachim Deutscher +2

This paper gives an overview of the control of distributed-parameter systems using normal forms. Considering linear controllable PDE-ODE systems of hyperbolic type, two methods der…

On delay-partial-differential and delay-differential thermal models for variable pipe flow

Jens Wurm, Simon Bachler, Frank Woittennek

A new formulation of physical thermal models for variable plug flow through a pipe is proposed. The derived model is based on a commonly used one-dimensional distributed parameter…
