Abstract:

The modeling and cooperative control method of mixed vehicle platoon consisting of both human-driven vehicle (HDV) and connected and automated vehicle (CAV) under multi-delay condition is studies in this paper. Firstly, a generalized model for mixed vehicle platoon system is constructed to characterize the number and spatial distribution of CAVs, with the time delay of driver’s response introduced into the model. Then, with consideration of V2V communication time delay and sensor measurement time delay, a state feedback controller is designed, the characteristic equation of the closed-loop system is derived, and the sufficient conditions for the closed-loop stability of the system are determined according to the Routh Hurwitz criterion to guide the parameter design of the controller. Finally, numerical simulation is conducted to verify the effectiveness of the controller design, quantitatively exhibiting the role of CAV in attenuating traffic fluctuation, with the effects of various time delays on traffic flow fluctuation analyzed.
