Operating cranes is challenging because payloads can experience large and dangerous oscillations. One of the solutions to reduce the sway oscillation of the crane payload is to use a passive damper. This method is simple but has limited effectiveness because without adaptability and flexibility to prevent adverse movements and amplify the favorable ones. This paper proposes an on-off damping controller for the semi-active damper to improve the passive damper. The on-off damping control aims to amplify the radial motion of the damper to increase the energy dissipated, then reduce the sway vibration. The effectiveness of the proposed controller is verified by numerical simulations of a 2D crane. |
