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…

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…
