This paper aims at putting forward an adaptive fuzzy hierarchical sliding mode control
method to deal with the control problem for uncertain under-actuated switched nonlinear …

As a class of underactuated systems, cooperative dual rotary crane systems (DRCSs) are
widely used to complete the task of large payload transportation in complex environments …

The control of underactuated Euler–Lagrange systems with uncertain and switched
parameters is an important problem whose solution has many applications. The problem is …

As the volume and the mass of the payload increases, it is often necessary to use two ship-
mounted cranes to jointly transport huge payloads under marine environment. Compared …

As typical mechanical transportation equipment, cooperative dual ship-mounted cranes are
widely used to transport large goods or containers in the marine environment. However, the …

Overhead cranes, which have been extensively studied, are mostly simplified as single
pendulums. However, in practice, the existence of lifting hook usually makes the crane …

Available control methods for underactuated Euler–Lagrange (EL) systems rely on structure-
specific constraints that may be appropriate for some systems, but restrictive for others. A …

Offshore cranes are complicated underactuated systems, which work in harsh sea
conditions. Due to the various severe disturbances, the control of offshore cranes has …

Unwanted oscillations caused by the operator-commanded motions lower the capable
operating speeds and degrade the safety of dual cranes moving distributed-mass payloads …

In industrial practice, to improve transportation capability, there has been increasing
applications for dual overhead crane systems (DOCSs). Compared with single overhead …
