On $\mathcal{L}_{\infty}$ string stability of nonlinear bidirectional asymmetric heterogeneous platoon systems
It offers a theoretical condition for string stability in complex platoon systems, which is important for automated highway systems but is an incremental extension of existing stability analysis methods.
This paper provides a sufficient condition for L∞ string stability in bidirectional asymmetric heterogeneous platoon systems with nonlinear coupling, and demonstrates its application through a numerical example that enables independent control design for each vehicle.
This paper is concerned with the study of bidirectionally coupled platoon systems. The case considered is when the vehicles are heterogeneous and the coupling can be nonlinear and asymmetric. For such systems, a sufficient condition for $\mathcal{L}_{\infty}$ string stability is presented. The effectiveness of our approach is illustrated via a numerical example, where it is shown how our result can be recast as an optimization problem, allowing to design the control protocol for each vehicle independently on the other vehicles and hence leading to a bottom-up approach for the design of string stable systems able to track a time-varying reference speed.
