Reinforcement Learning-based Receding Horizon Control using Adaptive Control Barrier Functions for Safety-Critical Systems

1 code implementation26 Mar 2024 Ehsan Sabouni, H. M. Sabbir Ahmad, Vittorio Giammarino, Christos G. Cassandras, Ioannis Ch. Paschalidis, Wenchao Li

Unfortunately, both performance and solution feasibility can be significantly impacted by two key factors: (i) the selection of the cost function and associated parameters, and (ii) the calibration of parameters within the CBF-based constraints, which capture the trade-off between performance and conservativeness.

Secure Control of Connected and Automated Vehicles Using Trust-Aware Robust Event-Triggered Control Barrier Functions

1 code implementation4 Jan 2024 H M Sabbir Ahmad, Ehsan Sabouni, Akua Dickson, Wei Xiao, Christos G. Cassandras, Wenchao Li

We address the security of a network of Connected and Automated Vehicles (CAVs) cooperating to safely navigate through a conflict area (e. g., traffic intersections, merging roadways, roundabouts).

Optimal Merging Control of an Autonomous Vehicle in Mixed Traffic: an Optimal Index Policy

no code implementations7 Nov 2022 Ehsan Sabouni, Christos G. Cassandras

We derive an optimal index policy which prescribes the merging position of the AV within the group of HDVs.

Optimal Control of Connected Automated Vehicles with Event/Self-Triggered Control Barrier Functions

no code implementations26 Sep 2022 Ehsan Sabouni, Christos G. Cassandras, Wei Xiao, Nader Meskin

We address the problem of controlling Connected and Automated Vehicles (CAVs) in conflict areas of a traffic network subject to hard safety constraints.

Self-Triggered Coordination Control of Connected Automated Vehicles in Traffic Networks

no code implementations24 Mar 2022 Nader Meskin, Ehsan Sabouni, Wei Xiao, Christos G. Cassandras

The safety constraints and the vehicle limitations are considered using the Control Barrier Function (CBF) framework and a self-triggered scheme is proposed using the CBF constraints.
