Contraction-based Observers using non-Euclidean Norms with an Application to Traffic Networks
Samuel Coogan, Murat Arcak
In this note, we study Luenberger-type full-state observers for nonlinear systems using contraction theory. We show that if the matrix measure of a suitably defined Jacobian matrix…
The Price of Anarchy for Transportation Networks with Mixed Autonomy
Daniel A. Lazar, Samuel Coogan, Ramtin Pedarsani
We study routing behavior in transportation networks with mixed autonomy, that is, networks in which a fraction of the vehicles on each road are equipped with autonomous capabiliti…
A Contractive Approach to Separable Lyapunov Functions for Monotone Systems
Samuel Coogan
Monotone systems preserve a partial ordering of states along system trajectories and are often amenable to separable Lyapunov functions that are either the sum or the maximum of a…
Approximating the Frequency Response of Contractive Systems
Michael Margaliot, Samuel Coogan
We consider contractive systems whose trajectories evolve on a compact and convex state-space. It is well-known that if the time-varying vector field of the system is periodic then…
