Funnel-Precompensated Disturbance Observer for Uncertain Minimum-Phase SISO Linear Systems of Arbitrary Relative Degree
Hyuntae Kim, Thomas Berger
Disturbance observers (DOBs) recover nominal behavior, but fast filters risk peaking. We propose a funnel-precompensated DOB for uncertain minimum-phase single-input single-output…
Event-Triggered Funnel Control for Output Reference Tracking of Unknown Nonlinear Systems
Janina Schaa, Thomas Berger
We propose an event-triggered zero-order hold implementation of the funnel controller for output reference tracking of unknown nonlinear systems. The control input is updated only…
Distance-Based Formation Control with Prescribed Performance for Higher-Order Multi-Agent Systems
Janina Schaa, Maria Charitidou, Dimos V. Dimarogonas +1
We consider distributed distance-based formation control with prescribed transient performance for multi-agent systems modeled by unknown nonlinear dynamics of relative degree grea…
Data-Based Analysis of Relative Degree and Zero Dynamics in Linear Systems
Janina Schaa, Thomas Berger
Data-driven control offers a powerful alternative to traditional model-based methods, particularly when accurate system models are unavailable or prohibitively complex. While exist…
Some Remarks on Positive/Negative Feedback
Thomas Berger, Achim Ilchmann, Eugene P. Ryan
In the context of linear control systems, a commonly-held intuition is that negative and positive feedback cannot both be stability enhancing. The canonical linear prototype is the…
An improved input-constrained funnel controller for nonlinear systems
Thomas Berger
We present an improvement of a recent funnel controller design for uncertain nonlinear multi-input, multi-output systems modeled by higher order functional differential equations i…
Funnel control -- a survey
Thomas Berger, Achim Ilchmann, Eugene P. Ryan
The methodology of funnel control was introduced in the early 2000s, and it has developed since then in many respects achieving a level of mathematical maturity balanced by practic…
Funnel MPC for nonlinear systems with relative degree one
Thomas Berger, Dario Dennstädt, Achim Ilchmann +1
We show that Funnel MPC, a novel Model Predictive Control (MPC) scheme, allows tracking of smooth reference signals with prescribed performance for nonlinear multi-input multi-outp…
