A Receding Horizon Approach to String Stable Cooperative Adaptive Cruise Control

A time domain approach to a "string stable", i.e., capable of attenuating acceleration shockwaves, cooperative adaptive cruise control is proposed in this paper. A receding horizon scheme is adopted to design a controller which attenuates acceleration shockwaves generated by the preceding vehicle while avoiding rear-end collisions. The classical definition of string stability in frequency domain is revised in the time domain and a new criterion for predecessor-follower string stability based on the acceleration signals is defined and used. Simulation and experimental results are presented to show the effectiveness of the proposed method.
