Linear Quadratic Regulator-Based Coordinated Voltage and Power Control for Flexible Distribution Networks

open access: yesEnergies
Multi-port soft open points (SOPs) are effective devices for alleviating issues such as voltage violation and transformer overloading in distribution networks caused by the high penetration of distributed energy resources.

Suboptimal Model Predictive Control With a Computation Governor: Stability, Recursive Feasibility, and Applications to Alternating Direction Method of Multipliers

open access: yesOptimal Control Applications and Methods, Volume 47, Issue 6, Page 1317-1328, November/December 2026.
Computational governor is shown which simultaneously adjusts the reference and adjusts the constraints. ABSTRACT The paper considers a computational governor strategy to facilitate the implementation of Model Predictive Control (MPC) based on inexact optimization when the time available to compute the solution may be insufficient.

Safeguarded Reinforcement Learning for Dynamic Environments

open access: yesOptimal Control Applications and Methods, Volume 47, Issue 6, Page 1543-1555, November/December 2026.
This paper uses a combination of Reinforcement Learning and Funnel Control to train a fast and safe controller for systems operating in changing environments. Furthermore, the presented formulation overcomes former limitations associated with the need for predefined reference trajectories.

Hamilton–Jacobi–Bellman Equations and Reinforcement Learning: A Theoretical Framework and Empirical Study for Dynamic Credit Decision-Making

open access: yesMathematics
Traditional credit scoring models treat lending decisions as static classification, ignoring the dynamic evolution of borrower risk and long-term profit optimisation.

Probing Strong Coupling in Core–Shell Nanoparticles With Fast Electron Beams

open access: yesphysica status solidi (a), Volume 223, Issue 17, 9 September 2026.
An exact analytic formalism for evaluating electron‐energy loss and cathodoluminescence probabilities for core–shell nanoparticles explored by electron‐beam spectroscopies is derived. The formalism is exploited to understand strong exciton–plasmon and exciton–Mie mode coupling in nanophotonic architectures.

Inertial‐Based LQG Control: A New Look at Inverted‐Pendulum Stabilization

open access: yesInternational Journal of Mechanical System Dynamics, Volume 6, Issue 3, Page 489-501, September 2026.
ABSTRACT Linear‐quadratic Gaussian (LQG) control is a well‐established method for optimal control through state estimation, particularly in stabilizing an inverted pendulum on a cart. In standard laboratory setups, sensor redundancy enables direct measurement of configuration variables using displacement sensors and rotary encoders. However, in outdoor
