A Review of Anti-Swing Control for Cranes

Abstract

Crane systems play a critical role in industrial operations, enabling the precise movement of heavy loads. However, the inherent complexities, such as pendulum-like swinging and dynamic instability, present significant challenges in their control. This paper provides a review of control strategies employed in crane systems, with a focus on achieving stability, safety, and precision. A feed-forward control strategies such as input shaping are discussed in term of the effectiveness in minimizing the payload swing. Other control approaches are explored for their ability to handle nonlinearities and disturbances. The review emphasizes the need for robust, adaptive control mechanisms that can solve the addressed issues.
