摘要

Purpose

To enhance the robustness and efficiency of overhead crane operations through the development and evaluation of modified input shaping techniques.

Methods

A comprehensive numerical analysis, supported by experimental validation, was conducted on an overhead crane system using two newly proposed input shaping methods: Minimum Vibration and Integral (MVI) and Zero Vibration and Minimum Integral (ZVMI). These shapers, based on harmonic input functions, were designed to allow selectable maneuvering times and accommodate varying cable lengths. Their performance was compared against established methods, including Zero Vibration (ZV), Zero Vibration and Derivative (ZVD), and Extra Insensitive (EI) shapers.

Results

The proposed MVI and ZVMI shapers demonstrated superior robustness and adaptability across a range of operational conditions, including variations in cable length and maneuvering time. Numerical simulations showed reduced residual vibrations and improved system performance, which were corroborated by experimental results.

Conclusion

The MVI and ZVMI input shaping techniques offer enhanced robustness and flexibility for overhead crane systems, making them effective tools for improving operational efficiency under diverse constraints. Their validated performance highlights their potential for practical implementation in industrial crane operations.
