Control Strategy with Synchronous Motion for Multi-cable System of Ship-mounted Crane
In response to the problem of synchronous motion between the anti-sway cables of the multi-cable system of a ship-mounted crane during lifting,luffing and external disturbances,it is difficult to achieve synchronous motion.Firstly,the kinematics and dynamics models of the multi-cable system of the ship-mounted crane were established,and then the fuzzy PID control strategy was proposed.Finally,the simulation analysis was carried out using MATLAB/Simulink software.The results show that under the fuzzy PID control strategy,the error between the desired length of the cable and the actual length of the cable of the multi-cable system gradually approaches zero,and the error between the desired speed of the cable and the actual speed of the cable gradually approaches zero.Compared to traditional PID control,the fuzzy PID control strategy has higher robustness.
