A Nonlinear CTH-Based Adaptive Cruise Controller With Safety and String Stability Guarantees
Dionysios Theodosis, Amirhossein Samii, Nikolaos Bekiaris-Liberis
This paper studies the problem of longitudinal control, with safety and string stability guarantees, in vehicle platoons. A nonlinear adaptive cruise controller based on the Consta…
Global Stability Analysis of the Age-Structured Chemostat With Substrate Dynamics
Iasson Karafyllis, Dionysios Theodosis, Miroslav Krstic
In this paper we study the stability properties of the equilibrium point for an age-structured chemostat model with renewal boundary condition and coupled substrate dynamics under…
Nonlinear Cruise Controllers with Bidirectional Sensing for a String of Vehicles
Iasson Karafyllis, Dionysios Theodosis, Markos Papageorgiou
We introduce a nonlinear cruise controller that is fully decentralized (by vehicle) and uses spacing and speed measurements from the preceding and following vehicles to decide on t…
From Road Congestion to Vehicle-Control Enabled Artificial Traffic Fluids
Iasson Karafyllis, Dionysios Theodosis, Markos Papageorgiou +1
This article provides an overview of the design of nonlinear feedback Cruise Controllers (CCs) for automated vehicles on lane-free roads. The feedback design problem is particularl…
Performance-Sensitive Potential Functions for Efficient Flow of Connected and Automated Vehicles

Two-Dimensional Cruise Control of Autonomous Vehicles on Lane-Free Roads
Iasson Karafyllis, Dionysis Theodosis, Markos Papageorgiou
In this paper, we design decentralized control strategies for the two-dimensional movement of autonomous vehicles on lane-free roads. The bicycle kinematic model is used to model t…
State Estimation for a Class of Linear Systems with Quadratic Output
Dionysis Theodosis, Soulaimane Berkane, Dimos V. Dimarogonas
This paper deals with the problem of state estimation for a class of linear time-invariant systems with quadratic output measurements. An immersion-type approach is presented that…
Nonlinear Adaptive Cruise Control of Vehicular Platoons
Iasson Karafyllis, Dionysis Theodosis, Markos Papageorgiou
The paper deals with the design of nonlinear adaptive cruise controllers for vehicular platoons operating on an open road or a ring-road. The constructed feedback controllers are n…
Analysis and Control of a Non-Local PDE Traffic Flow Model
Iasson Karafyllis, Dionysis Theodosis, Markos Papageorgiou
The paper provides conditions that guarantee existence and uniqueness of classical solutions for a non-local conservation law on a ring-road with possible nudging (or "look behind"…
Sufficient Lie Algebraic Conditions for Sampled-Data Feedback Stabilization
John Tsinias, Dionysis Theodosis
For nonlinear affine in the control systems, a Lie algebraic sufficient condition for sampled-data feedback semi-global stabilization is established. We use this result, in order t…
