  This paper deals with the design of resilient Cooperative Adaptive Cruise
Control (CACC) for homogeneous vehicle platoons in which communication is
vulnerable to Denial-of-Service (DOS) attacks. We consider DOS attacks as
consecutive packet dropouts. We present a controller tuning procedure based on
linear matrix inequalities (LMI) that maximizes the resiliency to DOS attacks,
while guaranteeing performance and string stability. The design procedure
returns controller gains and gives a lower bound on the maximum allowable
number of successive packet dropouts. A numerical example is employed to
illustrate the effectiveness of the proposed approach.
