Learning the Globally Optimal Distributed LQ Regulator
Luca Furieri, Yang Zheng, Maryam Kamgarpour
We study model-free learning methods for the output-feedback Linear Quadratic (LQ) control problem in finite-horizon subject to subspace constraints on the control policy. Subspace…
First Order Methods For Globally Optimal Distributed Controllers Beyond Quadratic Invariance
Luca Furieri, Maryam Kamgarpour
We study the distributed Linear Quadratic Gaussian (LQG) control problem in discrete-time and finite-horizon, where the controller depends linearly on the history of the outputs an…
System-level, Input-output and New Parameterizations of Stabilizing Controllers, and Their Numerical Computation
Yang Zheng, Luca Furieri, Maryam Kamgarpour +1
It is known that the set of internally stabilizing controller is non-convex, but it admits convex characterizations using certain closed-loop maps: a cl…
On the Equivalence of Youla, System-level and Input-output Parameterizations
Yang Zheng, Luca Furieri, Antonis Papachristodoulou +2
A convex parameterization of internally stabilizing controllers is fundamental for many controller synthesis procedures. The celebrated Youla parameterization relies on a doubly-co…
Sparsity Invariance for Convex Design of Distributed Controllers
Luca Furieri, Yang Zheng, Antonis Papachristodoulou +1
We address the problem of designing optimal linear time-invariant (LTI) sparse controllers for LTI systems, which corresponds to minimizing a norm of the closed-loop system subject…
On Separable Quadratic Lyapunov Functions for Convex Design of Distributed Controllers
Luca Furieri, Yang Zheng, Antonis Papachristodoulou +1
We consider the problem of designing a stabilizing and optimal static controller with a pre-specified sparsity pattern. Since this problem is NP-hard in general, it is necessary to…
An Input-Output Parametrization of Stabilizing Controllers: amidst Youla and System Level Synthesis
Luca Furieri, Yang Zheng, Antonis Papachristodoulou +1
This paper proposes a novel input-output parametrization of the set of internally stabilizing output-feedback controllers for linear time-invariant (LTI) systems. Our underlying id…
