This paper addresses the fixed-time predefined performance platoon formation control problem of automated vehicles with the consideration of uncertain disturbances. First, a general platoon formation control framework is developed. Then, the transformed errors are designed to make sure the predefined performance requirement is satisfied.

Aiming at the problem of low merging efficiency, poor platoon stability, and high collision risk when multiple connected and automated vehicles merge into the same target platoon, we propose a multi-vehicle self-organized cooperative control strategy for platoon formation, which includes vehicle self-organizing formation control and platoon cooperative merging control. The vehicle self-organizing ...Show More
This paper presents a novel distributed data-driven control scheme for the longitudinal formation control of a connected heterogeneous vehicle (CHV) platoon.

This brief focuses on the platoon formation control for a fleet of unmanned surface vehicles (USVs) with uncertain kinetics, unmeasured velocities, input saturation and dead zone to ensure collision avoidance (CA) and connectivity maintenance (CM).

This paper investigates the problem of prescriptive performance tolerant control of a heterogeneous vehicle platoon with intermittent actuator failures. A finite time prescribed performance function is then suggested, which makes use of the prescribed performance control (PPC) technique. This can prevent collisions and maintain connectivity between nearby ve-hicles while guaranteeing that the plat...Show More
This paper considers the problem of formation control design for a large platoon of identical vehicles, where the dynamics of each vehicle is described by a fully actuated double integrator.

This paper investigates a distributed data-driven event-triggered fault-tolerant control for a connected heterogeneous vehicle platoon with sensor faults under the vehicle-to-vehicle (V2V) communication network. First, a sensor fault diagnosis scheme based on the high-gain observer is designed to detect, estimate and compensate for the fault signal. Then, the measurement signals with sensor faults...Show More
