DOI: 10.1007/s13369-021-05340-0
Abstract: The double-pendulum (DP) phenomenon, effectuated by the fact that the payload configuration and the chain length between the hook and the payload are usually unknown, is a typical issue in actual cranes. This phenomenon is… read more here.

DOI: 10.1109/access.2018.2888563
Abstract: Overhead cranes with double-pendulum effect seem more practical than those with single-pendulum effect. However, in this case, the dynamic performance analysis and the controller design become more difficult. Moreover, achieving both high-precision tracking control and… read more here.

DOI: 10.1109/access.2021.3070048
Abstract: Because of the complexity, non-linearity, and under-actuated features of double pendulum overhead cranes, a control method based on linear active disturbance rejection control (LADRC) and differential flatness theory is proposed to realize accurate trolley positioning… read more here.

DOI: 10.1109/access.2023.3265586
Abstract: This paper proposes an anti-sway controller for two-dimensional overhead cranes. The controller is of the position-commanding type, i.e., it sends position commands to the position-controlled trolley, and it uses the sensor information of the payload… read more here.

DOI: 10.1177/01423312221105699
Abstract: During the synchronous operation of the double-container, the double-lift overhead cranes suffer from the perturbation of system internal parameters, friction and external unknown disturbances. To address the impact of the above-mentioned negative factors, based on… read more here.

DOI: 10.1177/1687814017720086
Abstract: In practice, vertical load motion is always involved in overhead cranes. In this case, the cable length turns from a constant to a variable, which may induce large amplitude load swing and make it more… read more here.
