The problem of feed-forward control overhead crane system is discussed. By combining the Kalman's controllability theory and Hartman-Grobman theorem from dynamical theory, a linear, continuous state feedback-based controller that stabilizes at desired end position payload designed. efficacy proposed demonstrated by comparing simulation experiment results for with/without time-varying length hoi...

Overhead cranes are widely used in industrial applications for material displacing. Many linear or nonlinear control schemes have been proposed for overhead cranes and implemented on electronic systems, but energy efficiency of transportation has seldom been considered in motion planning. This paper aims at finding an optimal solution of motion planning in terms of energy efficiency for overhea...

This paper presents investigations into the development of hybrid control schemes for input tracking and anti-sway control of a gantry crane system. A nonlinear overhead gantry crane system is considered and the dynamic model of the system is derived using the Euler-Lagrange formulation. To study the effectiveness of the controllers, an LQR control is developed for cart position control of a ga...

The study, carried out at the Batch Annealing Furnace (BAF) shop of Cold Rolling Mill (CRM) at an integrated steel plant of India, concerns ergonomic evaluation and redesign of a manually-operated Electrical Overhead Travelling (EOT) crane cabin. The crane cabin is a complex worksystem consisting of the crane operator and twelve specific machine components embedded in a closed workspace. A cran...

Abstract The paper presents a method of testing the girder bridge crane using specialized measuring type robot. is an example largesize structure. structure critical subsystem transport device due to its operational safety. purpose overhead tests increase reliability and proposed solutions indeed comply with standards in force. Also, they their frequency effectiveness concluding terms predictin...

The paper is devoted to the disclosure construction of SCADA system for managing operating modes and monitoring electric drive overhead crane. material provided in form step-by-step instructions building such a Vijeo Designer program. creation new project, interface elements, binding variables with setting behavior dynamic elements are shown detail. issue communication global variable visual M2...

This paper proposes a method to experimentally study the stressed state of metallic structure an overhead crane when using running wheels different designs. The employed functioning electric, supporting, double-girder with capacity 5 tons and run 22.5 m. Strain gauges assembled in semi-bridge circuit connected analog-digital converter Zetlab210 (Russia) were used determine girder deformations a...
