For practical mechanical systems, uncertainties/disturbances, such as unmodeled dynamics
and frictions, are nonignorable factors. For existing control methods, these factors are …

A maglev train is a sustainable public transport method with the characteristics of being
green, pollution-free, and low noise, as well as providing environmental protection …

The paper investigates a nonlinear vibration mitigation strategy of a variable length
pendulum subjected to a harmonic external excitation. A nonlinear absorber in a form of a tri …

An adaptive integral sliding mode control (AISMC) method with payload sway reduction is
presented for 4-DOF tower cranes in this paper. The designed controller consists of three …

To transfer heavy payloads at construction sites, tower cranes are essential. However, tower
cranes are a complex underactuated system due to the strong coupling between the jib …

This paper presents a robust passivity-based adaptive control method for payload trajectory
tracking of a three degree-of-freedom overhead crane with a varying-length rigid hoist cable …

A limited number of coupling-based works have been reported for stabilizing the overhead
crane subject to both parametric uncertainty and input saturation. Particularly, integral action …

When the double pendulum crane works in three-dimensional motion mode, it can
significantly improve transportation efficiency. However, controlling the two-stage swing …

The regulation and disturbance rejection problems of the underactuated overhead crane
system in the presence of uncertain disturbances are considered in this paper. A novel …

In this article, we design a novel saturated proportional-derivative (PD) with sliding-mode
control (SMC) method or saturated PD-SMC in short for 4-DOF tower crane systems under …
