Lateral-Longitudinal Prescribed-Time Cooperative Control of Vehicles Subject to Wear and Road Disturbance

This paper studies the lateral and longitudinal formation control issue of a collection of vehicles subject to wear and road disturbance. A novel prescribed-time disturbance observer is designed to estimate the unknown disturbance. Then, based on the disturbance observer, an adaptive nonsingular vehicle formation control strategy is proposed to ensure the formation errors converge to a close neighborhood of origin in a prescribed time, which can be confirmed in advance by specifying several simple parameters. Simulation results validate the effectiveness of the presented control method.
