报告摘要

The dynamic model of such vehicle systems is inherently nonlinear, and involves unknown and uncertain parameters due to wear-tear, ageing, and changes of road conditions and surrounding environments. A distributed direct adaptive control law is employed to control the vehicles' longitudinal motion, globally asymptotically stabilizing the operating point, specified by the speed limit. More importantly, a passivity approach is adopted to analyze the disturbance string stability associated with the platoon of adaptive closed-loop vehicle control systems. It is shown that the distributed direct adaptive control law achieves the string stability in the presence of model nonlinearities and parameter uncertainties against the worst-case energy bounded disturbances. Further analysis shows that the vehicle platoon under the distributed direct adaptive control law is capable of synchronizing all velocities while maintaining the required safe inter-vehicle distances. The results are illustrated by simulation studies compared with other existing methods for platoon control.
