Backstepping control of position synchronization system in crane lifter

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.
