Pendulation reduction on ship-mounted container crane via T-S fuzzy model

Ship-mounted container cranes are challenging industrial applications of nonlinear pendulum-like systems with oscillating disturbance which can cause them unstable. Since wave-induced ship motion causes the hoisted container to swing during the transfer operation, the swing motion may be dangerously large and the operation must be stopped. In order to reduce payload pendulation of ship-mounted crane, nonlinear dynamics of ship-mounted crane is derived and a control method using T-S fuzzy model is proposed. Simulation results are given to illustrate the validity of the proposed design method and pendulation of ship-mounted crane is reduced significantly.
