Dynamic performance analysis and controller design become more difficult when the load sway in rotary cranes exhibits double-pendulum characteristics. Furthermore, uncertain parameters and external disturbances in the crane system make it difficult for traditional methods to obtain satisfactory control performance.
Tion sites, most tower cranes are designed modularly, which enables a large number of boom configurations. The fundamental motions of tower cranes are slewing, hoisting and they also allow either a luffing motion or load travel. During operation, crane motions cause dynamic forces on the hoist load and on the crane’s structure.
