Backstepping Design of Dynamic State Feedback Controllers for Parabolic Systems
Nicole Gehring, Benedikt Schwämmle, Abdurrahman Irscheid +1
Recently, dynamic state feedback controllers that are based on dynamic extensions have been presented for heterodirectional hyperbolic systems. In this paper, a similar concept for…
Successive design of backstepping observers for parabolic PDE-ODE systems and its duality to state feedback stabilization
Nicole Gehring
The paper introduces a successive backstepping observer design for strictly feedforward parabolic PDE-ODE systems, in which the coupling structure determines the order of error sta…
Flatness-based control of a Timoshenko beam
Simon Schmidt, Nicole Gehring, Abdurrahman Irscheid
The paper presents an approach to flatness-based control design for hyperbolic multi-input systems, building upon the hyperbolic controller form (HCF). The transformation into HCF…
On the strict-feedback form of hyperbolic distributed-parameter systems
Nicole Gehring
The paper is concerned with the strict-feedback form of hyperbolic distributed-parameter systems. Such a system structure is well known to be the basis for the recursive backsteppi…
Using dynamic extensions for the backstepping control of hyperbolic systems
Nicole Gehring, Joachim Deutscher, Abdurrahman Irscheid
This paper systematically introduces dynamic extensions for the boundary control of general heterodirectional hyperbolic PDE systems. These extensions, which are well known in the…
Backstepping Control of Coupled General Hyperbolic-Parabolic PDE-PDE Systems
Joachim Deutscher, Nicole Gehring, Nick Jung
This paper considers the backstepping state feedback and observer design for hyperbolic and parabolic PDEs, which are bidirectionally interconnected in a general coupling structure…
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…
Backstepping-based tracking control of the vertical gradient freeze crystal growth process
Stefan Ecklebe, Nicole Gehring
The vertical gradient freeze crystal growth process is the main technique for the production of high quality compound semiconductors that are vital for today's electronic applicati…
Output Feedback Control of Coupled Linear Parabolic ODE-PDE-ODE Systems
Joachim Deutscher, Nicole Gehring
This paper deals with the backstepping design of observer-based compensators for parabolic ODE-PDE-ODE systems. The latter consist of n coupled parabolic PDEs with distinct diffusi…
On the Calculation of Differential Parametrizations for the Feedforward Control of an Euler-Bernoulli Beam
Bernd Kolar, Nicole Gehring, Markus Schöberl
This contribution is concerned with the motion planning for underactuated Euler-Bernoulli beams. The design of the feedforward control is based on a differential parametrization of…
Output feedback control of general linear heterodirectional hyperbolic PDE-ODE systems with spatially-varying coefficients
Joachim Deutscher, Nicole Gehring, Richard Kern
This paper presents a backstepping solution for the output feedback control of general linear heterodirectional hyperbolic PDE-ODE systems with spatially-varying coefficients. Ther…
An Algebraic Approach for Identification of Linear Systems with Fractional Derivatives
Nicole Gehring, Joachim Rudolph
Identification of fractional order systems is considered from an algebraic point of view. It allows for a simultaneous estimation of model parameters and fractional (or integer) or…
