(PDF) Nonlinear optimal control of a 3-D overhead crane

In this brief, we propose a nonlinear tracking control method of 3-D overhead crane systems which works well even in the presence of the initial swing angle and the variation of payload weight.

Fig. 1 Gantry crane system Fig. 2 Ideal gantry crane system Fig. 3 The computer controlled gantry crane system The overhead gantry crane system consists of a small crane that is driven by a DC motor in a horizontal direction along on I-beam that is approximately three meters long (See Figures 1 and 2).

The paper presents a mechatronics approach to elaborate intelligent control system of the real device: the two-spares overhead crane. The control system, based on fuzzy controller with Takagi-Sugeno-Kang fuzzy inference system, was elaborated, built and optimized during simulations conducted on mathematical models of the device and

Jan 01, 2018 · System model of crane operating mechanism A bridge crane is a mechanical and electrical system formed by metal mechanism, working mechanism (including motors), motor control system and payload.

Dynamics of an overhead crane under a wind disturbance

Jun 01, 2014 · The main part of the overhead control system with wind disturbance compensation is presented in Fig. 5. Load motion in a horizontal plane is possible owing to the overhead bridge crane traveling and traversing mechanisms. The input signals are as follows: – determined velocity of the bridge traveling mechanism v bg, –

Dec 01, 2007 · Various attempts in controlling gantry cranes system based on open- loop and closed-loop control systems were proposed. However, most of the proposed controllers were designed based on the model and parameter of the crane system. In general, modeling and parameter identifications are troublesome and time consuming task.

Jan 19, 2005 · The anti sway system control is incorporated in the main PLC control of the crane. The other is an open loop system which can prevent and dampen load movement induced sway, but cannot compensate for external influences as there is no feedback of actual load position. It is therefore intended for indoor use such as overhead cranes in factories.

The dynamic model of overhead crane is highly nonlinear and uncertain. In this paper, Takagi-Sugeno (T-S) fuzzy modeling and PSO-based robust linear quadratic regulator (LQR) are proposed for anti-swing and positioning control of the system. First, on the basis of sector nonlinear theory, the two T-S fuzzy models are established by using the virtual control variables and approximate method.

The aim of this work is to propose a flatness control of a crane detailing adopted mechanisms and approaches in order to be able to control this system and to solve problems encountered during its functioning. The control objective is the sway-free transportation of the crane’s load taking the commands of the crane operator into account.
