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

Advanced 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

Estimation of the Wind Load Required to Cause the Overturning of a Gantry Crane, Comparing Different Structures of the Main Horizontal Girder

Applied Sciences
The present paper concerns the problem of estimating the loading induced by the wind on a gantry crane standing in the open air. Sufficiently strong wind may cause the device to move or even tip over. Two different structures were studied, namely the box

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

Optimal 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.
