contents This paper presents a novel control design for vehicular formations, which is an alternative to the conventional second-order consensus protocol. The design is motivated by the closed-loop system, which we construct as first-order systems connected in series, and is therefore called serial consensus. The serial consensus design will guarantee stability of the closed-loop system under the minimum requirement of the underlying communication graphs each containing a connected spanning tree -- something that is not true in general for the conventional consensus protocols. Here, we show that the serial consensus design also gives guarantees on the worst-case transient behavior of the formation, which are independent of the number of vehicles and the underlying graph structure. In particular this shows that the serial consensus design can be used to guarantee string stability of the formation, and is therefore suitable for directed formations. We show that it can be implemented through message passing or measurements to neighbors at most two hops away. The results are illustrated through numerical examples.
