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

International Journal of Mechanical System Dynamics, EarlyView.
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

Robust Position Control of an Electro‐Hydraulic Actuator via Metaheuristic Optimization of a Fractional‐Order PID Controller

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT In this study, a robust position control strategy is presented for a two‐stage electro‐hydraulic actuator system using a fractional‐order proportional–integral–derivative (FOPID) controller tuned by Kirchhoff's law algorithm (KLA). Electro‐hydraulic systems exhibit strong nonlinearities, parameter uncertainties, and external disturbances ...

Real‐Time Fractional Control of an Electrohydraulic System Using Low‐Cost Technology

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Advances in control methods for electrohydraulic systems (EHS) improve performance by addressing nonlinearities and unknown parameters, although most studies are limited to numerical simulations. Furthermore, research with experimental validation often relies on high‐performance computing equipment, specialized data acquisition cards, and ...

Degradation of Crystalline Si‐Based Solar Modules With Varying Material Combinations—Part I: Encapsulant Degradation

Progress in Photovoltaics: Research and Applications, EarlyView.
This work deals with the degradation of solar modules with varying material combinations under accelerated aging conditions. By in situ moisture measurements and simulations of oxygen ingress, the consumption of stabilizing additives and polymer degradation can be correlated spatially resolved with the penetrating stressors.

Performance of pyDock in 8th CAPRI: Energy‐Based Scoring Applied to Docking and AlphaFold Models

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The 8th CAPRI edition has shown a significant evolution in the field of protein–protein complex structure prediction. We have participated in all 11 targets proposed in this edition, involving domain‐domain, protein–protein, protein‐peptide, and protein‐DNA interactions, including homo‐ and hetero‐meric interfaces.
