Network-Realized Model Predictive Control Part I: NRF-Enabled Closed-loop Decomposition
A two-layer control architecture is proposed, which promotes scalable implementations for model predictive controllers. The top layer acts as both reference governor for the bottom layer, and as a feedback controller for the regulated network. By employing set-based methods, global theoretical guarantees are obtained by enforcing local constraints upon the variables of the network and of the first layer's implementation. The proposed technique offers recursive feasibility guarantees as one of its central features, and the expressions of the resulting predictive strategies bear a striking resemblance to classical formulations from model predictive control literature, allowing for flexible and easily customizable implementations.

Closed-loop Data-Enabled Predictive Control and its equivalence with Closed-loop Subspace Predictive Control
Factors like improved data availability and increasing system complexity have sparked interest in data-driven predictive control (DDPC) methods like Data-enabled Predictive Control (DeePC). However, closed-loop identific…
From System Level Synthesis to Robust Closed-loop Data-enabled Predictive Control
The Willems' fundamental lemma and the system level synthesis characterize trajectories generated by a linear system. While the former method is valid for deterministic LTI systems, the latter one is further effective fo…
