“…The main difference is that here ISS is ensured with respect to all the ahead leader-follower pairs. This work extends to a general class of control systems the preliminary results introduced in [20], that were developed for a specific case study. Simulations show the positive effects of the utilization of macroscopic information on the whole traffic platoon.…”

“…We applied the general framework described in Theorem 1 to two different spacing policies. Rather than the philosophical choice of the desired spacing policy, we remark that the differences on the proposed control action in (62) and (72) mainly rely on the possibility to have the functions in (20) directly affecting the control input. A proper choice of the parameters a and b in (61) and (70) will size the realtime contribution of the macroscopic functions (57) and (58) with respect to the filtered version given by ρ i in (21).…”

We investigate the possibility to use macroscopic information to improve control performance of a vehicular platoon composed of autonomous vehicles. A general mesoscopic traffic modeling is described, and a closed loop String Stability analysis is performed using Input-to-State Stability (ISS) results. Examples of mesoscopic control laws are provided and shown to ensure String Stability properties. Simulations are implemented in order to validate the control laws and to show the efficacy of the proposed approach.

“…The present work is based on the framework developed in [10] and [11], and extends it to the case where disturbances act on each vehicle. A platoon of autonomous vehicles is considered, and a controller implementing a variable spacing policy exploiting macroscopic information is proposed.…”

“…A variable time spacing policy based on the shared macroscopic variables is defined, and stability of the platoon subject to external disturbances is proven by exploiting Input-to-State Stability (ISS) property in an inductive way. As in [10] and [11], the ISS property is ensured with respect to all the ahead leader-follower pairs of vehicles.…”

This paper exploits macroscopic information for the control of autonomous vehicles in platoon formation in case of external disturbances. The use of such information leads to a smoother platooning. A mesoscopic controller is proposed, and Disturbance String Stability is proven through Input-to-State Stability (ISS) concepts. Simulations prove the efficacy of the proposed approach by showing its robustness with respect to the presence of perturbations acting on the platoon vehicles.

This paper deals with large-scale interconnected systems with general network topology, affected by external disturbances, and with the possibility to ensure the overall stability when some sufficient conditions are met by each agent with respect to its neighbors. We introduce the notion of scalable Mesh Stability (sMS), that requires the existence of trajectory bounds that do not depend on the number of subsystems. The immediate consequence is that perturbations originating in a point of the interconnected system do not amplify through it. A numerical example on interconnection of microgrids shows the interest and the effectiveness of the theoretical result.
