Active damping control for bending oscillations of a forklift mast using flatness based techniques

摘要

Forklift trucks, such as the STILL FM-X ensure fast transport of heavy loads for logistics. The mast carriage of the FM-X can be shifted to increase the reachability of loads within a warehouse. Modern forklift trucks are constructed in a lightweight mode to increase their maximum operation velocities, load capacities, and to save costs. Hence, the mast has a limited stiffness and will be subject to oscillations of deflection. They are induced by the shifting of the mast carriage.
