Real‐time Nonlinear Model Predictive Control of a Robotic Arm Using Spatial Operator Algebra Theory

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Nonlinear model predictive control (NMPC) has inherent challenges, such as high computational burden, nonconvex optimization, and the necessity of powerful and fast processors with large memory for real‐time robotics. In this study, a new NMPC strategy is proposed using Spatial Operator Algebra (SOA) theory to address these challenges, and ...

Towards a Semiautonomous Young Spruce Forest Late Cleaning

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Cleaning a seedling spruce stand is an important silvicultural task required to help the young spruce trees thrive. It is usually manual work with a clearing saw. Mechanized solutions have been proposed, but they have not worked out well, since the driver has challenges in seeing the seedling trees that should be left growing.

Rate‐type and integral‐type sectional analysis for time‐dependent response with the fib Model Code 2020

open access: yesStructural Concrete, EarlyView.
Abstract This study examines the time‐dependent behavior of reinforced and prestressed concrete structures using integral‐ and rate‐type formulations, applying the concrete creep and steel relaxation models from the fib Model Code 2020. The stress–strain law for aging concrete is expressed by a second‐order differential equation, but a single rate‐type
