A Distributed Vision‐Based System for Cost‐Effective Fault Diagnosis of Modular Bridge Expansion Joints

Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.
Detecting faults in modular bridge expansion joints (MBEJs) is a critical challenge, as their complex dynamic behavior under operational loads is difficult to characterize with conventional methods. Existing monitoring approaches often face a trade‐off between high cost, intrusive installation, and an inability to capture the distributed kinematic ...

An Iterative Learning Control Technique for Point-to-Point Maneuvers Applied on an Overhead Crane

Shock and Vibration, 2014
An iterative learning control (ILC) strategy is proposed, and implemented on simple pendulum and double pendulum models of an overhead crane undergoing simultaneous traveling and hoisting maneuvers.

Robust exact linearization of a 2D overhead crane

IFAC-PapersOnLine, 2018
Abstract Cranes are widely used to transport loads. The dynamical models of most crane systems are differentially flat. The motion planning and the closed-loop tracking of a load reference trajectory can be addressed thanks to this flatness property. The tracking feedback law can be functionally separated into a linearizing inner feedback and into an

Dynamic Optimization Design of Cranes Based on Human–Crane–Rail System Dynamics and Annoyance Rate

Shock and Vibration, 2017
The operators of overhead traveling cranes experience discomfort as a result of the vibrations of crane structures. These vibrations are produced by defects in the rails on which the cranes move.
