Model predictive control (MPC) has been successfully applied to many transportation systems. For the control of overhead cranes, existing MPC approaches mainly focus on improving the regulation performance, such as tracking error or steady-state error. In this paper, energy efficiency as well as safety is newly considered in our proposed MPC approach. Based on the system model designed, the MPC...

Precise manipulation of payloads is difficult with large cranes. Oscillation can be induced into the lightly damped system by motion of the overhead support point, or from environmental disturbances. A combined feedback and input shaping controller is presented here. The controller uses feedback to detect and compensate for positioning error in the overhead support unit (e.g. the bridge or trol...

Due to the technological advances in computer hardware and software tools, structural optimization has been gaining continuously increasing interest over the last two decades. The purpose of the present work is to quantitatively compare three metaheuristic optimization algorithms, namely the Differential Evolution, Harmony Search and Particle Swarm Optimization methods, in the framework of stru...

Abstract Load swaying is one of the most frequently occurring problems at production sites. The purpose this work to create a control system for movement an overhead crane with anti-sway function. Particle Swarm Optimization method has been used find controller coefficients. function should be implemented using PLC (programmable logic controller) and have high speed operation. frequency convert...

The paper is concerned with the finite-time stabilization of a coupled PDE–ODE system describing motion an overhead crane flexible cable. dynamics cable described by wave equation variable coefficient which affine function curvilinear abscissa along Using several changes variables, backstepping transformation, and stable second-order ODE for conveniently chosen variable, we prove that global oc...

The problem of stabilizing vibrations of flexible cable related to an overhead crane is considered. The cable vibrations are described by a hyperbolic partial differential equation HPDE with an update boundary condition. We provide in this paper a systematic way to derive a boundary feedback law which restores in a closed form the cable vibrations to the desired zero equilibrium. Such a control...

The paper proposes a new approach to efficiently control three-dimensional overhead crane with 6 degrees of freedom (DoF). Most the works proposing law for gantry assume that it has five output variables, including three positions trolley, bridge, and pulley two swing angles hoisting cable. In fact, elasticity cable, which causes oscillation in cable direction, is not fully incorporated into mo...
