Improving Circular Path Control Using Extended State Observers for an Industrial Overhead Crane

open access: yesAdvanced Control for Applications, Volume 7, Issue 1, March 2025.
ABSTRACT In industrial overhead cranes, inverters and motors are used to control motor position, velocity, and acceleration. However, higher‐order derivatives depend on load characteristics, leading to inconsistent jerk profiles and deviations in circular path. Payload sway further contributes to path deviation, and although sway suppression techniques

Fast Nonlinear Model Predictive Control Combining Online Trajectory Optimization and Value Function Regression

open access: yesOptimal Control Applications and Methods, Volume 46, Issue 2, Page 709-725, March/April 2025.
The paper proposes a method to reduce MPC computation by shortening the prediction horizon using an approximate value function. A goal‐oriented sampling strategy is introduced that incorporates function values and gradients to train the value function, enabling efficient online optimization.

Treatment of inelastic material models within a dynamic ALE formulation for structures subjected to moving loads

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 126, Issue 1, 15 January 2025.
Abstract This article showcases the development of a dynamic Arbitrary Lagrangian Eulerian (ALE) formulation to account for inelastic material models within a finite element framework. Such a formulation is commonly utilized in research domains like fluid mechanics, fluid‐structure interaction, quasi static remeshing techniques, and quasi static load ...
