Multiobjective $H_{\infty }$ Control for String Stability of Cooperative Adaptive Cruise Control Systems

TLDR: The proposed control method solves an optimization problem and achieves a controller that is able to provide not only the system stability, but also the string stability as distinct from the traditional <inline-formula> <tex-math notation="LaTeX">$H_{\infty }$</tex- math></inline- formula> control.

Abstract: Autonomous vehicle following systems are playing a decisive role to increase vehicle density on roads by shortening intervehicle time gaps However, disturbance attenuation along a platoon of vehicles, ie, string stability, is being a challenging task while time gap is getting shorter In order to guarantee the string stability of a vehicle platoon, a multiobjective $H_{\infty }$ control formulation for adaptive cruise control and cooperative adaptive cruise control structures has been investigated in this paper The proposed control method solves an optimization problem and achieves a controller that is able to provide not only the system stability, but also the string stability as distinct from the traditional $H_{\infty }$ control
