Robustness of specific switching control laws for platooning
2023/03/01 - 2023/08/31
Vehicular platoon control can effectively achieve group consensus, reduced fuel consumption, improve vehicular running safety and increase road capacity. However,this emerging technology faces several challenges like unreliable vehicle-to-vehicle communications, sensitivity to road traffic and to additions/reductions in platoon size. A small gap results in a short inter-vehicular distance, which is fuel efficient when the vehicles are moving at constant speeds due to air drag reductions, but when the vehicles accelerate and brake a lot, a bigger time gap is more fuel efficient. Similarly, a poor communication network motivates a higher inter-vehicular gap for safety while a smaller gap can be maintained with reliable communications. All these issues motivate platoons that switch the control strategy according to the scenario [1,2]. However, while the string stability of a given control scheme is well studied [3], guarantees on a switching control are rarely examined.

The objective of this internship is to realize a numerical analysis of the switching control laws and prepare their theoretical analysis.
