FREQUENCY-MODULATION INPUT-SHAPING STRATEGY FOR DOUBLE-PENDULUM OVERHEAD CRANES UNDERGOING SIMULTANEOUS HOIST AND TRAVEL MANEUVERS

Frequency-Modulation Input-Shaping Strategy for Double-Pendulum Overhead Cranes Undergoing Simultaneous Hoist and Travel Maneuvers

Large payloads hoisted by overhead cranes exhibit the same behavior as that of a double-pendulum.Changes in the hoisting cable length during payload transfer maneuvers give rise to time-dependent system Painting frequencies rendering input-shaped commands ineffective.In this paper, a frequency-modulation input-shaping strategy that enables simultan

Bioenergy production and environmental impacts

Abstract Compared with the conventional fossil fuel, bioenergy has obvious advantages due to its renewability and large quantity, and thus plays a crucial role in helping defend the energy security.However, the bioenergy development may potentially cause serious environmental alterations, which remain unclear.The study summarizes the environmental
