Abstract

We introduce a mechanical control system for energy efficient and robust hoisting crane operations. The control system efficiently translates the harmonic motion of a spring loaded mediating system into the desired driving of the load, recyling most of the employed energy for subsequent operations. The control output is a shortcut-to-adiabaticity protocol borrowed from quantum mechanics. The control system reduces the single operation consuption in realistic working regimes, but it is in cyclical processes where the energetical advantage becomes substantial. The design of the control system and the control output is flexible enough to allow additional optimization of the robustness against perturbations.
