To solve the problem of crane anti-swing, fuzzy PID is a common method. However, parameter configuration requires lot time and effort from professionals. Based on this, we introduce LSO algorithm add stray operator, which effectively improves its global search performance. By combining SLSO comparing them with other methods, this paper confirms that even without targeted optimization by profess...

This paper deals with the uniform exponential stabilization of a hybrid PDE}ODE system which describes an overhead crane with #exible cable. A previous linear boundary feedback law (see d'AndreH a-Novel, Boustany, Conrad & Rao (1994). MCSS Journal, 1, 1}22) depending on the platform position and velocity and on the angular displacement of the cable at the connection point to the platform, led t...

While operating a crane for maximum productivity, the time of operation and the required energy are two important conflicting factors faced by a crane operator. In such a case, trying to reach the destination too quickly demands a large energy supply, while a small powered motion requires longer time. In this paper, we consider such a problem for two different pairs of objectives and employ a m...

In this paper, we design a fault diagnosis scheme for class of variable coefficient wave equation (an overhead crane system), which is composed an observer and its output error treated as residual signal. When the system in healthy state, signal decays exponentially. Due to existence external disturbance, not zero state without fault. Therefore, further reasonable threshold based on upper bound...

Selecting the best possible cranes and identifying spatial conflict-free locations on sites can result in productivity and safety improvements for large-scale industrial construction projects. In the current practice, experienced lift engineers select cranes based on the heaviest lift and/or the largest lifting radius of the identified crane. This practice is relatively time-consuming, and opti...

This paper presents investigations into the development of input shaping techniques for swaying control of a doublependulum-type overhead crane (DPTOC) system. A nonlinear DPTOC system is considered and the dynamic model of the system is derived using the Euler-Lagrange formulation. An unshaped bang-bang input force is used to determine the characteristic parameters of the system for design and...
