— In this paper we deal with the problem of stabilizing linear, time–invariant plants using feedback control configurations that are subject to sparsity constraints. Recent results show that given a strongly stabilizable plant, the class of all stabilizing controllers that satisfy certain given sparsity constraints admits a convex representation via Zames's(More)
Consider that a linear time-invariant (LTI) plant is given and that we wish to design a stabilizing controller for it. Admissible controllers are LTI and must comply with a pre-selected sparsity pattern. The sparsity pattern is assumed to be quadratically invariant (QI) with respect to the plant, which, from prior results, guarantees that there is a convex(More)
— In this paper we study state–space realizations of Linear and Time–Invariant (LTI) systems. Motivated by biochemical reaction networks, Gonçalves and Warnick have recently introduced the notion of a Dynamical Structure Functions (DSF), a particular factorization of the system's transfer function matrix that elucidates the interconnection structure in(More)

In this paper we deal with the problem of decentralized stabilization for linear and time-invariant plants in feedback control configurations that are subject to sparsity constraints. Recent theoretical advances in decentralized control have proved that the class of stabilizing controllers, satisfying a given sparsity constraint admits a convex(More)
We introduce a novel distributed control architecture for heterogeneous platoons of linear time–invariant autonomous vehicles. Our approach is based on a generalization of the concept of leader–follower controllers for which we provide a Youla–like parameterization, while the sparsity constraints are imposed on the controller's left coprime factors,(More)
