Abstract:

Enlightened by that the vibration can be suppressed by periodic structure, a periodic type control structure for vehicle platoon is proposed in this paper, with its interference suppression characteristics emphatically studied. First of all, the vehicle platoon model with periodic type control structure is established, and the external interference is introduced into the acceleration control input to construct the spacing error equation matrix of the whole platoon. Then the transfer function equations from external interference and leading vehicle disturbance to spacing following error are derived. Finally, the interference suppression characteristics of the vehicle platoon with periodic type control structure are analyzed by the maximum singular value of the spacing error transfer function matrix. The results show that the rational design of periodic type control structure can effectively reduce the peak of the maximum singular value of the transfer function matrix from interference to spacing error, and enhance the interference suppression capability of vehicle platoon, even for a heterogeneous one. In addition, the vehicle platoon with periodic type control structure also exhibits a good scale expandability.
