    Barrier function-based adaptive antisway control for underactuated overhead cranes

    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 possessing little capac...

    Finite-time command-filtered approximation-free attitude tracking control of rigid spacecraft

    In this paper, a finite-time command-filtered approximation-free attitude tracking control strategy is proposed for rigid spacecraft. A novel finite-time prescribed performance function is first constructed to...

    Energy coupled–dissipation control for 3-dimensional overhead cranes

    Handling loads with small swings is difficult for a 3-dimensional overhead crane due to its hard nonlinearity. Moreover, the nonlinear dynamics increases the complexity of the required feedback, thus making th...

    Automatic clustering based on density peak detection using generalized extreme value distribution

    Density peaks clustering (DPC) algorithm is able to get a satisfactory result with the help of artificial selecting the clustering centers, but such selection can be hard for a large amount of clustering tasks...
