Fixed-Point Constrained Model Predictive Control of Spacecraft Attitude
Alberto Guiggiani, Ilya Kolmanovsky, Panagiotis Patrinos +1
The paper develops a Model Predictive Controller for constrained control of spacecraft attitude with reaction wheel actuators. The controller exploits a special formulation of the…
Douglas-Rachford Splitting: Complexity Estimates and Accelerated Variants
Panagiotis Patrinos, Lorenzo Stella, Alberto Bemporad
We propose a new approach for analyzing convergence of the Douglas-Rachford splitting method for solving convex composite optimization problems. The approach is based on a continuo…
Forward-backward truncated Newton methods for convex composite optimization
Panagiotis Patrinos, Lorenzo Stella, Alberto Bemporad
This paper proposes two proximal Newton-CG methods for convex nonsmooth optimization problems in composite form. The algorithms are based on a a reformulation of the original nonsm…
