Structured linear quadratic control computations over 2D grids
Armaghan Zafar, Ian R. Manchester
In this paper, we present a structured solver based on the preconditioned conjugate gradient method (PCGM) for solving the linear quadratic (LQ) optimal control problem for $K \tim…

Model Predictive Control of Spreading Processes via Sparse Resource Allocation
Ruigang Wang, Armaghan Zafar, Ian R. Manchester
In this paper, we propose a model predictive control (MPC) method for real-time intervention of spreading processes, such as epidemics and wildfire, over large-scale networks. The…

Structured preconditioning of conjugate gradients for path-graph network optimal control problems
Armaghan Zafar, Michael Cantoni, Farhad Farokhi
A structured preconditioned conjugate gradient (PCG) solver is developed for the Newton steps in second-order methods for a class of constrained network optimal control problems. O…
