The offline path planning problem for arc welding robots becomes increasingly difficult to
achieve with the increasing product complexity and the open work environment, such as the …

In this work, the real-time optimal trajectory planning, together with a cascaded tracking
controller, is presented for a three-dimensional (3D) gantry crane in an environment with …

In this paper, a novel periodic sliding mode control method is designed for 4-DOF tower
crane systems with unmatched disturbances as well as unknown/time-varying control …

In this paper, we consider the application of the disturbance observer technique and
interconnection and damping assignment passivity-based control to the disturbance …

Efficient control of underactuated systems has always been a great challenge, since one has
to stabilize both actuated and unactuated states with fewer control inputs. During the past …

For the multi-rope structure of the container crane system and its large mass payload anti-
swing positioning problem, an equivalent double-swing model based on radial spring …

In recent years, wheeled bipedal robots (WBRs) have become one of the frontier fields of
robotic research, attracting immense interest from scholars globally. They can not only move …

Currently, due to the increasing complexity of industrial processes, obtaining precise
dynamic models for cranes is challenging. Cranes often operate in complex environments …

It is an important engineering safety problem to control the swing of the suspended objects
of container gantry crane. As an important construction machinery for logistics transportation …

Nonlinear controls that account for constraints on the state variable of overhead cranes can
hardly strengthen the effective coupling between trolley movement and load oscillation, thus …
