  We address the design of decentralized feedback control laws inducing
consensus and prescribed spatial patterns over a singular interacting particle
system of Cucker-Smale type. The control design consists of a feedback term
regulating the distance between each agent and pre-assigned subset of
neighbours. Such a design represents a multidimensional extension of existing
control laws for 1d platoon formation control. For the proposed controller we
study consensus emergence, collision-avoidance and formation control features
in terms of energy estimates for the closed-loop system. Numerical experiments
in 1, 2 and 3 dimensions assess the different features of the proposed design.
