Title:

Port-Hamiltonian car-following models under stochastic perturbations: stability and control

Abstract:

In this talk, I present a synthesis of three research articles on car-following models with a port-Hamiltonian structure, at the crossroads of mechanics, control theory, and probability. The port-Hamiltonian framework, rooted in engineering, provides a natural setting for describing energy exchanges within a system of interacting vehicles and capturing collective behavior. 

The uncontrolled dynamics turn out to be inherently unstable under stochastic perturbations, and an external speed control allows the system to stabilise and converge weakly to Gaussian limit distributions. This convergence is unconditional when the control is constant, but a non-trivial stability condition emerges when the control acts as a dynamic feedback depending on the distance to the preceding vehicle. Throughout, the theoretical results are supported and illustrated by numerical simulations.
