  "abstract": "This disclosure describes a system for anti-sway control in crane operations, addressing the challenge of load oscillation caused by varying rope lengths. The system utilizes real-time measurements of rope angle and length to dynamically generate an acceleration and deceleration profile for the crane's load-carrying mechanism. This profile is continuously adjusted to match the natural period of oscillation of the suspended load, minimizing sway during and after load movement. The approach ensures effective sway reduction across the full range of operational rope lengths, improving stability and operational precision without relying on fixed tuning parameters.",
