Anti-sway control for flexible tower cranes

ANTI-SWAY CONTROL FOR FLEXIBLE TOWER CRANES

Since the load sway motions of tower cranes are almost undamped, it is a demanding task to steer the loads safely and stop them at the target position without residual sway. Anti-sway control systems assist the operator to actively damp the load oscillations which can improve safety and handling performance. Since tower cranes are usually built as large lightweight constructions, they exhibit a limited stiffness that leads to notable structural oscillations. The structural dynamics represent a challenge for feedback control design, since neglecting them can lead to instability so they need to be taken into account explicitly.
