Stress analysis of gantry crane cylinder structure

Journal of Physics: Conference Series, 2022
Abstract By building three finite element analysis models for its four-bar metal structure under different amplitudes (the boom span is 13.5m, 22.5m and 34.5m), the relationship between stress, amplitude and load at key parts is established by linear interpolation method; At the same time, the relationship between the measured strain ...

On Gain Scheduling Trajectory Stabilization for Nonlinear Systems: Theoretical Insights and Experimental Results

International Journal of Robust and Nonlinear Control, Volume 35, Issue 6, Page 2142-2155, April 2025.
ABSTRACT Steering a nonlinear system from an initial state to a desired one is a common task in control. While a nominal trajectory can be obtained rather systematically using a model, for example, via numerical optimization, heuristics, or reinforcement learning, the design of a computationally fast and reliable feedback control law that guarantees ...

VISION BASED CONTROL OF GANTRY CRANE SYSTEM

Anadolu University Journal of Science and Technology-A Applied Sciences and Engineering, 2018
Heavy materials handling requires a sophisticated tool for efficient and optimum operations. In recent times, gantry cranes are considered as a dependable choice in terms of handling capacity, effectiveness, timeliness and safety. However, positioning of a trolley to the desired set point as fast as possible within minimum time without overshoot and ...

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
