Sample Complexity for Evaluating the Robust Linear Observers Performance under Coprime Factors Uncertainty
Yifei Zhang, Sourav Kumar Ukil, Andrei Sperila +1
This paper addresses the end-to-end sample complexity bound for learning in closed loop the state estimator-based robust H2 controller for an unknown (possibly unstable) Linear Tim…
Sparse Representations of Dynamical Networks: A Coprime Factorization Approach
Şerban Sabău, Andrei Sperilă, Cristian Oară +1
We study a class of dynamical networks modeled by linear and time-invariant systems which are described by state-space realizations. For these networks, we investigate the relation…
Network Realization Functions for Optimal Distributed Control
Şerban Sabău, Andrei Sperilă, Cristian Oară +1
In this paper, we discuss a distributed control architecture, aimed at networks with linear and time-invariant dynamics, which is amenable to convex formulations for controller des…
Sample Complexity of the Robust LQG Regulator with Coprime Factors Uncertainty
Yifei Zhang, Sourav Kumar Ukil, Ephraim Neimand +2
This paper addresses the end-to-end sample complexity bound for learning the H2 optimal controller (the Linear Quadratic Gaussian (LQG) problem) with unknown dynamics, for potentia…
A Parallel Linear-Constraint Active Set Method
E. Dov Neimand, Serban Sabau
We present two parallel optimization algorithms for a convex function . The first algorithm optimizes over linear inequality constraints in a Hilbert space, , and the…
Distributed Control of Descriptor Networks: A Convex Procedure for Augmented Sparsity
Andrei Sperilă, Cristian Oară, Bogdan D. Ciubotaru +1
For networks of systems, with possibly improper transfer function matrices, we present a design framework which enables control, while imposing sparsity constr…
Decoupled Dynamics Distributed Control for Strings of Nonlinear Autonomous Agents
Serban Sabau, Irinel-Constantin Morarescu, Lucian Busoniu +1
We introduce a distributed control architecture for a class of heterogeneous, nonlinear dynamical agents moving in the "string" formation, while guaranteeing trajectory tracking, c…
Optimal distributed control for platooning via sparse coprime factorizations
Serban Sabau, Cristian Oara, Sean Warnick +1
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 con…
H-infinity control problem for general discrete-time systems
Sebastian F. Tudor, Cristian Oara, Serban Sabau
The paper considers the suboptimal H-infinity control problem for a general discrete-time system (whose transfer function matrix is allowed to be improper or polynomial). The param…
A Novel Description of Linear Time--Invariant Networks via Structured Coprime Factorizations
Serban Sabau, Cristian Oara, Sean Warnick +1
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 introduc…
Stabilizability and Norm-Optimal Control Design subject to Sparsity Constraints
Serban Sabau, Nuno C. Martins
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-sel…
