Backstepping control of position synchronization system in crane lifter

Abstract
Aimed at the problems, such as the poor synchronization performance of heavy crane being operated coordinately and huge amounts of on-line calculation using the existed relative coupling strategy, a position synchronization controller based on adjacent relative coupling strategy and backstepping is designed. The simulation model is constructed in Matlab/Simulink environment, and the Simulink results show the position synchronization control system has a better position synchronization behavior and a quick convergence rate.
