The paper discusses about upgrading the overhead crane anti-sway method base on induction motor torque control from rotor resistance starter to variable frequency drives (VFDs). included two phases. phase 1 is identify performance of operation using (old existing starter). 2 that use a drive (new primary equations connecting tractive force and load sway angle, which law based designed for 0% wo...

This paper proposes a Takagi-Sugeno (TS) fuzzy approach for 2-dimensional of freedom overhead crane. Since this system is underactuated with nonlinear mathematical dynamic model, the requirement achieving accurate positioning while eliminating oscillation challenging issue. The sector decomposition taken into implementation which uses terms in model as scheduling variables to transform initial ...

When suspended payloads are moved with an overhead crane, pendulum like oscillations are naturally introduced. This presents a problem any time a crane is used, especially when expensive and/or delicate objects are moved, when moving in a cluttered and/or hazardous environment, and when objects are to be placed in tight locations. For example, one nuclear waste-handling operation examined by th...

A fuzzy logic controller with the fuzzy knowledge base: scaling factors of the input/output variables, membership functions and the rules are optimized by the use of the genetic algorithms, is presented in this work, and its application in the highly nonlinear systems. The fuzzy structure is specified by a combination of the mixed Sugeno’s and Mamdani’s fuzzy reasoning. The mixed, binary-intege...

To solve the problem of information acquisition of an industrial overhead crane, this paper uses an industrial camera to get the information. The information includes the height and the swing angle of the hook and the distance between the hook and the cargo. To obtain the real-time data of the hook’s height and swing angle, firstly the whole image captured by the industrial camera is processed ...
